As I was looking at a map of DC area I noticed the Theodore Roosevelt Island which I am sure I have seen before on the map but never really paid much attention to and wondered how one gets there considering that it seems even less accessible than the Jefferson Memorial. The island is accessible only via footbridge from Virginia yet reside within the District of Columbia. It is also part of the George Washington Parkway and therefore maintained by the National Parks Service. I guess I'll have to visit this soon!
