US Air Force missile launch site converted over into a state park site in North Dakota; wanna go visit the silo and play twist-the-key? (Multimedia tour online)
The missile site, about three miles north of Cooperstown and about 70 miles northwest of Fargo, is one of a handful of U.S. locations that commemorate the Cold War. The National Park Service operates a former Minuteman II launch center and missile silo in South Dakota. In Arizona, historic preservationists operate a former Titan nuclear missile site.
