Our Thursday destination was D.C.
Brandon and I each chose a museum that we wanted to see that day and both museums (African American and Holocaust) required tickets for entrance so we had to pick another museum to explore that day, which ended up being the National Museum of Natural History.
Brandon's favorite part of the museum... rocks. Sadly we got to that part of the museum 10 minutes before closing so we had to do a quick walk through, but I promised him that we would go back so we can spend the hour that he would have wanted to spend there.
Hung around for about an hour after the museum closed because it felt so nice out and because we didn't feel like dealing with the rush hour traffic.
