Late one afternoon we stopped in at National Museum of American History. Evan napped through our entire visit. We saw the Star Spangled Banner (a famous flag). In the American Stories gallery we looked at Dorothy's red slippers from the Wizard of Oz movie. We walked through the First Ladies Gowns and The American Presidency exhibit. Viva, Jake, and Lincoln took a ride in a simulator.
We took photos of the Capitol building and the Supreme Court building, but did not go in. There wasn't enough time to go into all the famous buildings in D.C. (I haven't been in all of them and I've been to D.C. nine times and I make it a goal to see new places every time I visit!)
