Washington, D.C. ~
I highly recommend visiting the International Spy Museum. This was one of the most fascinating museums I’ve been to in a while. Sure, art and culture are all around D.C. (for free), but this museum is totally worth paid admission, which is reasonable. I personally have an interest in the history of intelligence practices, and in the cultural and political forces that shape our world today. Fundamentally, people are people, and will go to great lengths for their beliefs.
