Library of Congress was up next - we took a tour led by a very knowledgeable woman with a delightful British accent. It's a beautiful building with lots and lots of authors and leading scientists, etc. of the day on the walls and such. After that was the National Botanic Garden which had a lot of neat-looking flowers and plants and such. Then we went to an art gallery which was sufficiently underwhelming that I don't remember its name.
We were pretty tired by this point so we went to Dupont Circle and had dinner at a trendy-looking place. Top Gun was playing on a big TV (although no sound), oddly enough.
Sunday we stayed at home, played a little WoW but mostly relaxed and read. I bought Man in the Middle by John Amaechi (the first NBA player to come out, albeit after his career was over), which was pretty interesting, and we both managed to get through it yesterday. We're saving the new Harry Potter for the big trip in September but I've mostly forgotten what happened in book 6 so we're listening to that again, which makes car trips more fun :-)
I just got a time off award at work (24 hours!), so yay for that!
