The Smithsonians were the undeniable favorites for our family when we were in Washington D.C. recently. We did two museums in one day (it turned out to be our longest day for the kids). Dinosaurs reigned supreme at our first stop at the Museum of Natural History so by the time we got to the Museum of American History, excitement had waned just a bit. All the museums do a fantastic job of being kid friendly. One of the features in the American History museum is the eras of our history are portrayed in lifelike scenes. A train on the tracks, a streetcar, a shop... and there are mannequins adding to the realness of these events. My girls, especially Evelynn and Caelan thought this was the best part. I managed to snap several photos of them joining the scenes.
