Washington D. C.
We took the Metro into Washington DC and had a great walk around the National Mall. The National Mall is nearly 2 miles long and over 1,000′ wide in some areas. So, it is really large and would entail a lot of walking to do all of it. So, we started about half way at the Washington Monument and went towards the Lincoln Memorial. From the World War II Memorial you can see the US Capitol Building peaking up over the horizon behind the Washington Monument.
