The final day of the conference was only a half day. We were on the metro into DC by 1:00 PM planning on spending the rest of the day at the National Mall. Unlike the previous two days, it was HOT and HUMID. It made the sky beautiful for pictures, but I thought I was going to die of heat stroke.
We got off at the Smithsonian stop which is located in the middle of the Mall and headed east towards the Capitol Building. Unfortunately, they were doing some construction nearby and preparing for an event (4th of July?) on the grounds which interfered with my pictures.
I was last in DC in 2000. A few new memorials have been constructed since then, including the World War II Memorial.
We also visited the Korean War Memorial, which I had not seen the last time I was in DC.
After all was said and done, we walked a little over 5 miles in gazillion degree heat that afternoon. We had dinner at a wonderful farm-to-table restaurant (Birch and Barley) near the White House and returned to the hotel around 11PM. It was a great day of sightseeing on my final day in Washington DC. I returned home on a 9am flight the next day.
