Lance and I walked to the Smithsonian Natural Science Museum. We got to see really cool stuff like the Hope Diamond:

and a bunch of other minerals and gems. Lance got to see a bunch of bugs, while I went to the bathroom. Apparantly these bugs were living and there was a huge roach on exhibit. He took pictures for me/to gross me out. We didn't get to stay very long in this museum, though, because we had to hike back to the American History museum to meet the rest of our group.
