Minuteman Missile National Historic Site features exhibits telling the story of the nuclear missile silos that were located throughout southwestern South Dakota. The visitors center includes memorabilia and displays that tell the story of the arms race from the 1960s through the present day, as well as the experiences of the people who lived through the times. Down the road, there is a control center and a missile silo that can be toured, but, at the time I visited the park, they were closed.
