Fodor's Expert Review Minuteman Missile National Historic Site

Treaties with the Soviet Union caused the removal of the nuclear missiles that formerly stood ready to launch in underground silos across western South Dakota, but one silo and disarmed missile, and its underground launch-control facility, were preserved as part of this historic site. The site consists of three spots along a 15-mile stretch of Interstate 90: a modern visitor center, which is full of exhibits about the Cold War, and the silo and launch-control facility. The visitor center and silo are free and open to the public, but there's a fee and a required reservation for the launch-control tour.
