Plant a tree and fight global warming (7/17/2019)

I wish it was so easy!

Boy, it is getting warmer on this blue marble floating in space. During the women’s soccer (or football) championships in France, they were complaining about record temperatures in Europe, and by this weekend, our temperatures are going to reach close to 100 degrees Fahrenheit, or 37.8 Celsius. As I write this (July 17, 2019), there was a news flash that Miami recorded the warmest low temperature early in the morning (84 Fahrenheit or 28.9 C). 

Thank goodness, nature is still able to cope with these extremes in our area. Where we live we have had approximately 6 inches (150 mm) more rain than average by this time of the year. At least there should be enough water in the deeper layers of the soil for at least the trees and other deeper rooting plants, but I may have to supplement the shallow rooted plants. 

Our ferns underneath the dogwood in our yard.  These ferns were dug up (saved) by my wife at a construction site she was permitting.  These ferns would have been destroyed if she had not dug them up. Now they are protected by our gargoyle and thanking us for our effort.  This is an example of plants that need supplemental watering because they don't root very deeply.

One way plants deal with the excessive heat is through evaporative cooling. Plants sweat, just as we do. Except with plants, we call it evapotranspiration. With us, sweating is an active thing, or at least with me it is. I actually get really wet when it is hot outside, and that is a great way of cooling, albeit somewhat embarrassing in public at times. Plants do not get wet, but they open their stomata (small mouth like openings) on their leaves and water evaporates though it, thus cooling the warming leaves. Most plant leaves are also very thin and small, which keeps them close to the air temperature prevents them from heating up in the direct sun light (like your car) and burning up. Pine needles are very good at this, which is why they grow throughout the southeast US. However, different plants have different ways of doing this. Some of you may have heard of quaking aspen; leaves from these trees start to shake (or quake) when the get too hot and they cool down that way. Cacti in the desert have a lot of water in their flesh that helps them in heating up very slowly. Moreover, the spines of cacti serve as suntan lotion and absorb radiation. The saguaro cacti also have fins that serve as cooling fins on the sides that are not hit by the sun. 

These are what we biologists call some of the different strategies that plants use to deal with heat stress. However, plants can only adapt or strategize that much! Eventually it gets too hot! In the tropics, some plants have adapted to that as well. They drop their leaves and go dormant, just like our trees do in winter when it gets too cold. However, there has to be enough water in the soil and they have to have stored enough energy to grow back when the temperatures get more hospitable, otherwise, they die. They usually grow back in the rainy season. Finally, here we have not even talked about how increased temperatures may also cause an increase in pests and diseases. You get the message. 

So, what is going to happen to the natural world or plants in our times of climate change? Alternatively, am I allowed to call it global warming, which is what it is? I frame this question this way, remembering that every time I mentioned global warming 10 or even 5 years ago in my workshops, I had students either rolling their eyes writing terrible reviews of my classes. There were at least one or two students that complained how I was “pushing my liberal agenda.” So I changed my tune and called it climate change and the complaints lessened over time. Guess what? Nowadays, I can talk about global warming again! 

For someone like me, who grows bonsai, life becomes more challenging. We use a much more porous growth medium that does not hold water. This means that we may need to water two times per day. Then those small pots can warm up very quickly and cook the roots, or at least give a leg up to mold and diseases. As you can see, it can be a challenge. 

For nature, it is another thing. I am only briefly going to write about plants and forest today and actually, we are not completely sure, but we can make a very solid educated guess. Plants in the northern hemisphere that live on the southern margins are going to have a challenge. What I mean is that they are already being challenged by the heat and cannot handle it much hotter. They will eventually disappear from the heat. This could be because they can no longer produce any viable seed, or because they simply die from heat stress. Somehow, nature will need to replace them and the problem is that native plants cannot move north fast enough to fill in the spots that have been opened up. These spots are often filled by invasive alien species. It is expected that invasive alien species will be able to take over larger tracks of land. The problem is these plants are often not very nutritious for local wildlife and insects. 

So what can we do about global warming, that is in addition to being political active and voting? The New York Times published an article not so long ago where they estimated that the planet has room for about 2.5 billion acres of forest that can be planted. While this will help in removing some carbon and reducing global warming somewhat, it is not enough. Can you imagine planting a forest of this size? So what can we do? Well, we can plant trees around our homes. If you are a loyal reader, you know I have been on a crusade against folks who cut trees around their home as soon as they move into our neighborhood. Trees are so much more efficient in fixing carbon than lawn. In addition, they modify the climate around your home. There is another interesting article about all this in a recent New York Times. So yes, in addition to growing my miniature trees, I also grow large trees in my small yard, although this makes it often difficult for me to find it difficult to find a sunny spot for my miniature trees.

On Environmental Ethics (5/12/2017)

In a LinkedIn group I am a member of the question came up: “Can an environmental consultant who works for industrial companies or land developers be ethical?”  My answer was a resounding yes. 

In my classes I use an example that goes like this:

During my consultant years, I was sitting behind my desk and Mike the head of our planning group walked into my office.  “Jan, can you attend a meeting next week with a client?  We are going to show him this new sub-division we have designed for him here in Virginia Beach.”  “Sure Mike, can I see the plans, so I can prepare myself a bit?”  Mike returns to my office in a few minutes with the plan.  “Mike, I have been on the property next door, and it has a lot of wetlands.  I want to bet this property probably has wetlands, as well.  I have not done a wetland delineation for this site, shouldn’t we do one?”  “Oops ...  OK Jan, why don’t you go and take a look.”  I go out the next day with my equipment and GPS, find a lot of wetlands on the site, survey them and stick them on a map.  The next day I walk into Mikes office.  Mike goes: “Oops.  Can you make them go away?”  I say: “Sure Mike, lots of money.”  At this point light bulbs go on above the heads of the students in my class.  They are paying attention now, I teach mostly government officials and I now work for the government.  He is finally going to expose the non-ethical corrupt industry of land development that he used to be part of, here it comes, they think!  But I tell my class: “No, when you are working with wetlands, the permitting and mitigation process is time consuming and very expensive and it is better to avoid it.  But if they want to build it the way Mike wants to propose it, the process will cost a lot of money for mitigation and permitting”  That is also what I tell Mike.  And the story continues from there, there was nothing unethical in my proposal.  Mike calls the client, asks for a a for more weeks of time and redesigns the site to avoid the wetlands.

I am proud to say that I have always been ethical in the work I have done.  Often my clients have done a little bit more for the environment than the laws and regulations required they should (thanks to me).  I have tried to show them the beauty and the importance of the resources.  In one case, I found the largest water oak in Virginia on a client's property.  A photo of my client under the tree made it in the local newspaper.  You bet that oak and the surroundings was saved, whether that client was ethical or not.

Ethics is defined as the moral principles that govern a person’s behavior or the conducting of an activity.  As a study it is the discipline that deals with what is good and bad and with moral duty and obligation (Merriam Webster Online Dictionary).  That is a mouth full, isn’t it?  Here you get to the argument of what is is!  Or what some people think is good or bad may differ from other people.  

There is a whole branch of philosophy devoted to ethics so it is not something I can contribute to; I am just a naturalist, biologist and trainer.  But I can try to live ethical or at least as ethical as possible.  This is what ethics studies:  "What would a person do or how would she/he react under a specific circumstance?"    

But I want to get back to environmental ethics and my job.  An argument can be made that I helped my clients check that box either on an application for a permit or maybe in the back of their conscious saying: "Yes, they have done their environmental due diligence."  I am not even talking about the best thing for the environment.  Like with Mike in that example above, I may have saved a few wetlands, but that subdivision still got build, birds, snakes, and turtles lost their home, the environment was still impacted.  As a consultant with sincere love for the environment the Serenity prayer was my escape hatch:

"Please give me the SERENITY to accept the things I cannot change, the COURAGE to change the things I can and the WISDOM to know the difference!"

That Serenity prayer kept me going, I could not change the outcome, but I had the courage to make a little bit of difference.  That made me feel better.

Even in my current job; I teach people and companies to follow the laws and the regulations.  It makes me feel good, when I get back to my motel room or back home, I feel satisfied; I ticked off those boxes of being a environmental steward, good for the environment.  But does it really help what I do?  I don't know.  I have often said and written that I would feel great that on any specific day in one of my classes of 40 individuals I have 1 or 2 people either change their attitude towards nature or actually become enlightened.  That's when I feel successful.

Often this is what we in the environmental movement need to look for.  No, we cannot stop a project but we can make reduce or minimize the environmental impact of these projects.  Those are our small ethical victories, save the world one turtle at a time.

We cannot stop development and that is not what my job is about.  We just need to make sure that it is done sustainable, responsibly and according to the laws and regulations.  Here my colleague Don and I are inspecting a building site.  We did not find much wrong here.

And we march on (4/24/2017)

And so the Nation marched for science, scientists, science funding and last but not least for Earth Day.  Yes, we marched as well.  No, we did not go to Washington DC this time but we marched in Norfolk.  Our very lame excuse was that the march ended up at the O’Conner’s microbrewery, which brews some of my favorite beer, like I needed an excuse to visit their tasting room again. 

Marching down Granby Street in Norfolk in the name of Science, Curiosity and Earth Day!

Get-together after the march at O'Connors microbrewery

Whatever my excuse was guys, marching and letting our voices heard was important, and maybe showing up in Norfolk was more important than doing so in DC.  Here we could show that the concern was nationwide, as it should be.  The concern is even more urgent so close to the Chesapeake Bay.  Science should not be a partisan thing; neither should be a concern for mother earth, or as I have called it in a previous post: our Blue Marble.  What concerns me is all this talk about future generations when we talk about saddling future generations up with economic debt, but very few want to address the fact that we are saddling future generations up with environmental debt. 

As I mentioned in previous posts these discussions are not new.  Malthus (1798) predicted that we would have to deal with over population and the resulting man-caused disasters (see my previous post about that <here>).  Others claimed it is our world and we can do with it what we want.  Western man’s dominion of nature is as old the bible itself.  But it was Francis Bacon (1561-1626) who articulated this when he claimed that we needed to use science and technology to reclaim our “dominion over creation”; something we had lost when Adam and Eve were "kicked" out of the Garden of Eden.  As I wrote in a May 11, 2016 blog post, John Locke took this a few steps further, and asserts that nature itself has no intrinsic value, but that nature only gains value when we work it.  

This is completely contrary to some of the work I did some 20 years ago which was called "natural resources damage assessment" or NRDA.  One of the questions asked in NRDA is about what the enjoyment of nature is worth to you (the public) personally.  It was particular important in cases like oil spills.  The question became how much enjoyment did that take away from you, because you could not spend time on that beach, or fish?  This goes into the equation to calculate the amount of fines that are being assessed to companies that damage the environment like BP when the had the spill in the Gulf.  If we would follow John Locke's logic the ocean may not be worth anything, or for that matter neither would the Chesapeake Bay.  Or maybe since we are mining it we have dominion over it and we can pollute it to our heart's content.

I think this strange logic is still out there, 500 years later.  Or is it 2000 years later?  Some people still think we can do to the earth what ever we want.  They think we own it.  There is still this thought that any problem can eventually be solved by science, a somewhat Baconeque point of view.  

Instead of seeing nature as a subordinate or worthless, we should have a sense of awe and wonder over nature, and a belief that we humans are part of it.  This is why we were marching this past Saturday, not only to solve these issues by science but to understand the issues (and maybe help with a solution).  By understanding them we maybe able to avoid worsening some of them or avoid starting new ones.  

On a final note, what encouraged my wife and I the most was that during our walk, some of the walkers were actually picking up garbage and eventually deposited the garbage in a dumpster that the found on our route.  They were actually cleaning up the environment as we walked, leaving the world a better place.

Speeches before the start of the march in Norfolk, just an interesting juxtaposition showing that science is apolitical

On Environmental Sustainability (8/11/2015)

On April 1, we premiered a new class that I developed on the use of plants in erosion and sediment control and stormwater management.  When we announced the class it was still in the design stage and I had hoped it would have even more emphasis on native plants than it did; but looking through all the materials on the books, I felt there was such a tremendous need for a more comprehensive approach to the use of plants and planting that it quickly became a much broader class for people reviewing construction plans and inspecting construction sites (and that from someone not formally schooled in landscape architecture or planning).  Honestly, I am still not sure I cover the entire issue, but what can you do in a six hour class?

It is well recognized that with the increased population throughout the U.S., there is a tremendous pressure on the natural (land) resources.  The cartoon below illustrates this very well.  I use it very often in my classes.

This is actually a sad cartoon, but I think this cartoon is applicable wherever you live: Yorktown, Richmond, or even Dallas (TX).  I have this nagging feeling that we are allergic to moving into the inner-city or older homes and renovating them, but that we all want that new home out in the suburbs, away from what we would consider riffraff.  With it of course comes abandoned buildings, increased city blight, urban sprawl, traffic jams, road rage, and environmental degradation, just to name a few negatives.  The great exception I have seen lately is Cincinnati where we visited in April this year.  Boy what a difference 15 years make, people are finally moving back into town and it has become so vibrant.  I am sure there are other examples as well.

A photograph I took in Over the Rhyn in Cincinnati in April.  The area has been revitalized; all kind of small independent shops and even small chains have moved in, and is an amazing place to hang out. When we lived in Cincinnati more than 15 years ago you would not go to this area.

The photo below shows an example of what I mean when I write about the move to the suburbs and urban sprawl.

Built three (3) years ago, the grass had a hard time getting established in this yard, after the soil was abused during the building process.  This yard had 40 to 50 year-old trees and shrubs growing in it.  They were all cleared in favor of grass (they left those three trees against the fence, or did they misjudge the property line when clearing the site?).  We have been walking by this yard for three years wondering what landscaping they were going to add, but you guessed it.  You can see the surrounding yards where the neighbors left some of the trees.  In addition to being an ecological desert, this house has no shade and I am sure their air conditioning bills are much higher than my home which is surrounded by trees.

I am sure this is a well built home; it was was built three years ago in an infill lot in our neighborhood.   Previously it was a wooded lot with mature trees that were at least 45 years old.  The site was completely cleared or as I called it in my classes "nuked," and just seeded with grass.  That's all!  To me this yard has absolutely zero ecological, biological, or environmental value.  It is a biological desert!  Before this one small infill lot was the home to birds, snakes, frogs, salamanders, turtles, insects, raccoons, rabbits, opossums, mice, etc., and now, I don't think even a bird would want to live in that yard.  Let's not talk about aesthetically value as well.  Boy, can I be any blunter?  But it is not only this house, I see it everywhere.

But you still see this everywhere, a forested track gets cut, turned into a subdivision with 5- to 10-acre lots that are all completely turned into lawn with no trees or when there are trees growing on it they are introduced and have very little ecological value for native animals such as birds and other critters.  Moreover, we fertilize and chemically treat the lawns so that they become net exporters of chemicals and pesticides, while in the past the forests that were growing there absorbed all the chemicals and exported oxygen, clean air and life.

We have a choice how we treat the land don't we?  Even when we want to live in the suburbs.  Landscaping can be done responsibly with humans and all the critters in mind.  I am sure that the people in the home of the photograph above did not choose this landscape with the thought of intentionally messing (or f...ing) up nature, but they obviously did not know any better; do no have the resources; cannot be bothered; are taking the easy way out; or in the worst case have no pride (I am sure you can come up with a few more reasons).

Steve Allison writes that we choose the world we create in our landscaping decisions; it is not only an ethical decision, but of course also a financial and often a maintenance decision as well.  But the question remains: why not do the best for the environment?  I understand that from a builder's/developer's perspective that there is a profit motive; we all need to make a living; and yes I am generalizing here, but I would like to see more people who are proud of their work and more concerned about future generations.  Money is not the end all; actually in the end we can not take it with us any way, but we can leave a legacy of a great ecologically sound landscape for future generations.  I know I am generalizing here; however, I also know there are people who are proud of their work.  I have met them and it was fun working for and with them.

In many of the books and reports that I read, I am told that we humans have reached the level where we are changing the world's environment.  We are the only species on the earth that can do this, all others have to adapt to the environment.  So instead of only changing it for the worst, why not try to change it for the better, or at least try not to have any impact at all?  Yes, we need to build and live, but let's do it with nature instead of against nature.

Virginia Beach (6/9/2015)

What a difference a decade makes.  I was at this location more than a decade ago to do an environmental inventory, and it was a contaminated site that needed some serious work.  Development was encroaching and there was a tremendous pressure to do something with the site.  I'm so happy to be here now and see what the Chesapeake Bay Foundation has done with it.

A view of the Lynnhaven river from the Education Center.  Interestingly, when I got my sailboat five and a half years ago it came out of the inlet in the back.  The boat could not get out at low tide and we had to pull her over a sand bar.  The problem was it could not go under the bridge any other time; the mast was too tall. 

The site now has the Brock Environmental Center and we are giving a stormwater class in their class room.  The building is LEED certified (platinum), they used good environmental site design, recycled materials,  do not use city water, generate the majority of their own electricity and have composting toilets.   Yes, that in the middle of Virginia Beach!

One of the two windmills that are estimated to produce 40% of the electricity for the Center.  Solar cells on the roof generate the rest.

It is pretty impressive,  the building has been designed to take advantage of the environment while still being protective against the elements, in particular global warming, sea level rise, and just increased flooding events.

Looking outside, you can see that the site is surrounded by tidal wetlands and what looks like a salt marsh community.   I can remember that one would not eat oysters coming from the Lynnhaven; the water they grew in was too polluted.  Currently,  Lynnhaven oysters are a delicacy, prized for it's salty, but delicate taste.  So great to see we are making progress in cleaning up the Bay; albeit very slowly and very localized.

James River (12/1/2014)

I posted a small write up on the James River approximately 9 months ago (click here if you like to see that one).  However, here I go again.  It was such a beautiful day on Monday that I had to go for a walk that took me again along the James river in Richmond.  It was great to meditate on the old railroad bridge that juts out over part of the river and think about the force of that water and about where all those drops of water have been.  You can think about where the drop was introduced into the watershed, or even become more philosophical about it and wonder where those molecules have been in the past.  Were they in a drop of sweat that was beading up on the forehead of Leonardo da Vinci or where have those molecules been in the past.  I have mused about things like this before in a blog I did that I called George Washington's shovel.  But water is an amazing thing; without it life is not possible.  Moreover, the way it freezes is important.  If it froze like any other substance would when it cools down, life would be impossible.

We teach that of all the water in the world only 6% is available to us.  All the other water is locked up in ways that we cannot get to it.  Of the 5.85% is in the oceans, leaving only 0.15% usable/fresh water.  Of this fresh water two thirds of it is locked up in glaciers and the remaining is either groundwater or fresh water.  In other words 0.05% of the water on earth is available to us for consumption.  I guess this is why I am always a bit upset when I watch people water their lawns, and especially so when they do it with valuable drinking water.  It is such a waste in my eyes.

Anyway, this another picture of the James.  One of these days I am going to create an extensive post on the river; showing pictures of it's origin (headwaters) to it's outfall into the Bay.  The picture below shows the jumble of the various bridges that go across the river: the road bridge and the I-95 bridge in the far back; the old pilings of a railroad bridge to Petersburg within the back a railroad bridge to Danvville and on the side the main track from Lynchburg.  A virtual spaghetti bowl of bridges and ruins of bridges.  What amazes me that they were able to build them on the spot where the river goes over the fall line.  Just looking at the force f the water amazes me.

Gainesville, VA (9/4/2014)

When I travel for work, I go to a place to teach a class or participate in the teaching in a stormwater related class.  That is why I am always excited to go to the offices of Wetland Studies and Solutions Inc. in Gainesville (the Manassas area).  In building their office, the owner has made sure that they constructed a building that is LEED certified (for the layman this means it meets very high environmental and energy efficiency standards) and that it manages stormwater the way we teach it.  It is a great place for show and tell (and no, I am not endorsing them; I just like the way they built their office; they are friendly and I hear they are a good company). 

So what do I teach?  This time I was teaching an erosion and sediment control plan review course for people in local government.  In it they learn about the various measures that control erosion from construction site.  In addition, they learn about managing stormwater that runs off construction sites and form sites where construction is done and the people have moved in.

Teaching all this can be frustrating and gratifying at the same time.  It is a required class if you want to work in the field, and you always have the very few that think that it is a waste of time.  They obviously do not believe in it.  Some even want to debate anything you say that has a slight slant towards environmentalism.  Conversely the majority goes through the motions; and then you have the few that really like it.  But I am happy to report that the reviews that I get from my teaching are generally very favorable.  I really try to make my classes relevant, interesting and I try to stay very dynamic in my classes.  There is nothing worse than having to go to a class and the teacher puts me to sleep.  It means; however, that I am exhausted after a day of teaching.

Anyway, we teach about the importance if infiltrating water back into the soil.  Far too often we see that rainwater/stormwater is treated like the enemy.  People connect down spouts to the storm sewer or to a drainage ditch and pipe it out of there.  In addition to disastrous results downstream the water does not go back into the soil where it belongs and we are now noticing dropping ground water table.  Moreover, we then also have to irrigate our lawns with drinking water.  It is all so backwards, that it often infuriates me.  At home we have three operational rain barrels and one waiting to go on line; in the summer we hardly ever water our plants with drinking water.

Back to this photograph; the building I taught at has a green roof. The roof has a growing medium on top of the roof that is 3 to 6 inches thick.  Plants are planted in the growing medium and the plants use the stormwater that falls on the roof.  Any excess rainwater is captured in a cistern, but a lot of the rainwater never leaves the roof.  Because of this, the roof is much cooler, which means lower air conditioner cost.  In the winter the thick layer of growing medium results in lower heating bills.  I took this photograph on the roof.  It has a narrow path and even two pick nick areas.  Great for show and tell.  (A previous post by me and picture of the roof can be found here)

 

Farmer's Market (8/9/2014)

Every Saturday in the spring, summer and fall we have a farmers market in Yorktown.  We go at least a couple of times a month to buy vegetables, fruit and occasionally some seafood.  We either go by bike, or we go by car.  When we go by car we bring the dogs and take them for a walk along the waterfront.
There is all kinds of things available at the market, from wine to BBQ spices to art; you name it.  there are even a few home bakers that sell their ware.But truthfully I am not that interested in that.  In the past years I served on the board of the Virginia Food Systems Council a great organization that encourages the reduction of food deserts, the consumption of regionally grown food, and in that way keeping the carbon footprint as small as possible.  An organization they worked closely together with was the Virginia Farm to Table group.
Both groups are wonderful and I really encourage people to explore their websites.  One campaign they had was the $10 per week campaign, where people pledge to by at least $10 worth of locally grown food.
Anyway here are two photos of our market.  It was a great day and yes we took the dogs.  There were all kinds of dogs; most of them were friendly.  There was even an older gentleman taking pictures of all the dogs.

Library of Virginia in Richmond (4/16/2014)

An article in the newspaper got me steaming today.  It was about how conservative USA (read Grover Norquist and the Koch brothers) are trying to stop the use of alternative energy and selling back of home generated energy back to the power companies.  Honestly, I think the newspaper was trying to fill some space, since this appears to be old news.  A simple search for Koch and renewable energy or solar energy shows their opposition to it for at least the past two or three years.  Guess they don’t like the government subsidies and the fact that there are laws requiring energy companies to buy back the excess energy that is generated at home.  I’m really nor that sure why they are against renewable energy.  Is it affecting their income as share holders in energy firms?  Or is it a principle, in that, energy conservation has been championed by more liberal thinkers and democrats, so it must automatically be bad and opposed?  I am still confused why those people who want to protect our children from a future deficit, have no problem in saddling those same kids up with a warmer planet, more polluted air, energy shortages, rising energy costs and a higher cost of living. 

So I was still steaming during my lunchtime walk in the sun (it was a great day to harvest solar energy).  It was abnormally chilly today, but it actually felt invigorating.  Walking up the hill at the capitol I noticed a saying on the Library of Virginia: “Reason and free inquiry are the only free agents against errors, …”  This saying is attributed to Thomas Jefferson, and it rang so true this afternoon.  We hopefully will use reason and inquiry before accepting everything that we are told, be it from conservative or liberal pundits. 

In full disclosure; I am the proud owner of two solar arrays that I will be installing on my sailboat, partially as an experiment, but also to be more self sufficient and less dependent on an outlet to charge the batteries on my boat.

Yorktown (4/13/2014)

It was absolutely beautiful on Sunday, and we decided to go for a walk with the dogs in Yorktown proper.  We parked up in the higher part and already when we opened the car door we were welcomed by the sound of bells ringing from the Baptist Church.  I assume it’s a large speaker system that puts the sound out over the village, but still it set a good atmosphere for Sunday morning.  When we got to the river (around 9:30), people were already staking their claim on the beach.  Also there were the guys with their metal detectors, looking for the things yesterday’s crowds had lost in the sand.  We had a great walk along the water and back up to the car.  In all we walked more than 7000 steps according to the fitbit that I wear, which is pretty darn good since my goal is 10,000 steps.  As I tell people, I am trying to get my girlish figure back, but it is a struggle, especially after a weekend of gluttony and wine tasting.

Yorktown is full with older buildings some of which are owned by the park service and others by individual.  There are also not so old homes, and even some older apartment buildings.  It is a nice combination, and a pleasure to walk.   The photo here is from the Nelson House, which dates from 1730 (here is another reference for the Nelson House).  It is a nice historic building that gives you a flavor of the importance of Yorktown in its hay days.  It’s amazing how fleeting some of these things such as fame and fortune can be, and only some will be kept in our memories forever.  People build monuments to themselves, such as ex-governor Nelson who seems to have built the largest house on Yorktown, or maybe the largest surviving house in Yorktown.  Guess we still do this in modern time, but I assume that most of the McMansions here in the US that are stick built, will eventually deteriorate, and few will remain as monument to their owners.  This is so very unlike the Europeans who built with brick and stones and where you still see many old buildings.

Now in modern time we have other means of leaving a legacy or our own monuments.  Some do it with the (non-biodegradable) trash they throw out of their car or fill the landfills with (my wife and I generate less than 2 bags of trash each week and compost all our food waste).  Others do it by writing, blogging or maybe even through things like facebook, twitter, or any other electronic way.  It should be interesting to see what will remain 100 or more years from now.  I personally hope that some of my writing (a few book chapters on scientific items), this blog, my photos on flickr or even facebook will give me some form of immortality.

Oh well, enough rambling.  We walked back by the beach an hour later, we were tired; the dogs had been swimming in the river and were wet.  Metal detector guys were gone and there was nothing left for future archeologists.  A lot more people were on the beach, ready to enjoy our first really warm day in the sun.
