Saturday was rainy (really the only rainy day I had the whole trip), but was ok because spent most of it inside at the Natural History Museum. Lots of really cool stuff in here, I think I enjoyed this more than the Air and Space Museum. When I was done looking around I went to have lunch; there were no free tables so sat down at one where a guy was going to be leaving soon. We started talking (his name was Paul) and offered to keep me company out to Pentagon City and the Pentagon, after he had a look at the Hope Diamond.
Paul and I caught the train out to the Pentagon station (useless trivia - they have the same train ticket machines as Sydney), where I took a photo of the Pentagon in the rain (yay). The picture they have in the foyer is the best view you get of the building. They also have tours but being a Saturday they did not have any running. We then walked up to the Pentagon City shopping mall, then caught the train back into town. Walking past a hotel spotted an ice sculpture just sitting there, very pretty :)
