In December, my Dad got tickets to tour the U.S. Capitol. They just opened a new Visitor's Center. This is #8 on my list. I didn't get very many picture inside. It's a huge open space with lots of natural light and lots of great exhibits. It's worth the trip.
It also happened to be the day my family was celebrating my birthday, so after we went to a fabulous little Mexican place behind the Library of Congress. I took the family on a tour of the tunnels under the Capitol and the Library of Congress.
In January, I started with #22 - Tour the DAR (Daughters of the American Revolution). They have a small museum collection and a bunch of rooms done up in different time periods. AND they have a library. It's in an old theater, so it's pretty unique.
