Minuteman Missile National Historic Site

I kicked off the Rocky Mountain region of my Summer 2021 trip with a stop at an actual nuclear missile silo just north of the Badlands. I was not lucky enough to get a tour of the Delta 01 facility down to the launch room, but they keep the Delta 09 site open a self guided tour about 20 minutes from the main visitor center where you can look down in an actual (previously) working nuclear missile silo.
