Lonely Minuteman Missile
Lewistown, Montana
A solitary deactivated Minuteman Missile stands in Lewistown's park, reportedly well-tended by the town. The Minuteman was a Cold War-era intercontinental ballistic missile, nestled in a silo deep in America's center to give the US government maximum dawdling time before responding to an inbound Soviet attack.
The Minuteman installation at Malmstrom Air Force Base, just north of Lewistown, was visited by a UFO in early 1967; maybe the missile is a warning to space invaders to back off.
