On our recent trip to Mount Rushmore, we came across a very interesting National Park to visit.
There is a Welcome Center that explains the Nuclear arms program as well as the different types of missiles that our government has in storage.
The Minuteman Missile was an iconic weapon in the American nuclear arsenal. It held the power to destroy civilization, but acted as a nuclear deterrent which maintained peace and prevented war.
It's not a big area, but it's interactive and they are working at expanding the displays.
This was a very interesting side trip. I highly recommend visiting if you are in the South Dakota area. Tickets are limited for the Base tour each day, but there is no charge. You need to visit the Welcome Center first, and get your tickets there.
