Arlington National Cemetery

[halfwright]

I don't know of any on the Virginia side, On the Maryland side, we stayed at Greenbelt National Monument. There is a big commercial park, Cherry Hill, near there. Old peoples pass at Greenbelt means $8/night compared to 50 and up at commercial parks. Greenbelt has no hookups, but there are faucets scattered around and a dump. We were touring DC all day and only needed a place to sleep, so it worked well for us.
