We also stopped off at the Smithsonian National Museum of Natural History where we not only saw their crystal skull but also walked through their live butterfly exhibit, where several of the magnificent creatures landed on my son's head (my 10-year-old daughter thinks it's because of his bright red hat).
We also ventured through the Smithsonian's Air and Space Museum . . .
. . . where we saw the actual hatch from the Apollo 11 capsule (below) along with other mind-bending artifacts.
We finished the day in Chinatown . . .
Tomorrow, we'll spend one more day on the Mall. I'm grateful to our out-of-town friends, because we'd begun to take for granted our proximity to D.C. and all its offerings. It's an amazing place.
