|We found The Cherry Hill RV park in College Park, MD just outside of Washington D.C. I chose it because of it's location and amenities for visiting D.C. The Metro Shuttle Bus picks up at the RV Park and drops at the Metro Train. The Transit system here is second to none. It's so easy and so clean! Today we visited the Spy Museum. We sat with a local on the train who turned out to work for the Secret Service and he highly recommended it (no surprise there). I thought the admission was a bit pricey, but we enjoyed it! Expect to spend about 2-3 hours in order to see and experience everything and don't be surprised if you find yourself looking at people and things a little more closely and suspiciously after you leave.
