On my visit to DC, I saw more than friends and kittens - I saw some of the city, and photos to prove it are posted.
Something I like about the city is the height restriction for the buildings. I think everything is shorter than the Capitol spire. I'm sure that does amazing things to the property values (as does the rock solid economy in the area). But it makes for nice foot traffic city visits. Human scale architecture in America. Amazing!
I really enjoyed The National Gallery of Art on the north east side of the Mall. Since my visit was during the heat wave that hit the east coast in July, I especially liked any place with great air conditioning. Stepping outside felt just like home in Houston, Texas - 110+ temps and 90% humidity. But more about the museum: think "endowed" instead of "publicly funded". It is such a great visit, both the pre-modern and modern buildings.
One interesting piece is a painting by Leonardo Da Vinci, of an American young woman, in Virginia. Who knew? It's so very Italian, and so provincial early American.
Library of Congress. Smithsonian buildings. Architectural salvage. Eastern Market on a Saturday morning. Shopping in Alexandria. I think Georgetown escaped my photographic documentation this trip. You know, a good mix.
I'm looking forward to my next trip.
