If you are in Washington, you must visit the National Museum of American History. This museum is one of the many Smithsonians in the DC area, which means free admission and absolutely fantastic exhibits. You'll find everything from Mr. Roger's sweater and Archie Bunker's chair to gowns worn by many First Ladies. The traveling exhibits have ranged from the history of computers to a tribute to paint-by-numbers. You'll need most of a day if not a full day to visit, but no need to hurry. It's free!
