Minuteman Missile National Historic Site, Philip

For those of us who lived through the Cold War, these sites were legendary. They provided the backbone of America's defense(?) capabilities, silos in the middle of nowhere buried underground. The museum/visitor's center is easily accessible from the Interstate, on the same exit as the east entrance to Badlands. The missile site is a few miles away and well worth the 30 minutes it takes to see it. Getting tickets to the command center is tough, as they give out on 24 per day and stay booked up. It is a fascinating look at a dark time in our history.

This place was really entertaining and informative. The parking lot is actually very large and the RV parking isn't far away like most places. The only sad thing was we didn't even know about it till we got to the area and we saw a sign... So we weren't able to do the guided Delta 1 tour. Apparently it's recommended to make reservations up to 90 days in advance.
