Two things that really surprised me:
1) The city streets were SO EMPTY! There was hardly any traffic, and no crowds at all. Such a quiet city...who knew!?!
2) This city is so clean. We must have walked ten miles all over the city (no lie)...and I did not see any graffiti at all.
Have you been to DC in the past? What were some of your favorite places to visit while in town?
