We also had the opportunity to visit a few of the Smithsonian Museums. We didn't have time to go through them in detail, but the Museum of Natural History and the National Air and Space Museum were definite favorites.
We also spent a morning at the National Zoo. I really enjoyed that. A nice stroll in a place that ALL the kids loved. Evan had a ball making all sorts of animal sounds. :)
Tomorrow...the trip to the beach! Stay tuned.
