A little history I find fascinating: Google Maps List of Nike missile sites - Wikipedia More ghosts from a bygone era, these being in (relatively) recent memory. There are a couple sites close to me. I haven't been to the actual missile silos, but I have hiked up to some locally famous cliffs where the radar installations were. There's not much left there now, just some old concrete pads, dilapidated buildings, and washed out Army Corps of Engineers Jeep access roads. All of these missile sites and radar installations were built during the Cold War, in preparation for a nuclear war with the Soviet Union that (thankfully) never happened. As crazy as our current times are, in a way I'm glad I didn't grow up in the times when children were drilled at school to hide under desks to be shielded from a nuclear blast. Here's a couple pictures from the former radar installation near me: Google Maps Google Maps Google Maps
We did a little desk-ducking practice in school. I used to wonder what the use of that was, considering how destructive the bomb is. Today, I live within a mile as the crow flies from a Nike missile site. It is located at the end of a road called "Missle Site road." I imagine the Soviets would neve have figured that one out!  (Probably had a different name at one time, I would guess.)
Yeah these are really cool. There's a few in Wisconsin. One was right in the parking lot of a former employer of mine..
I’m originally from the next town over from Loring AFB, my uncle, married to the family, was a B-52 pilot there and met my father’s sister. We were allowed on the base on special occasions when we were kids, once we got to go into one of the B-52s. Awesome sight for a 5 year old kid. It is said there are still active missals in the area because of the location as the most north eastern base in the US. I can’t confirm anything but I have seen some of the places that are maintained and heavily fenced in. Never see any activity around it. This is all farm land area as well so it really does not fit in. There’s a large radar array outside of Mars Hill as well that is still maintained. Sometime when I have time to stop I’ll see if I can get some pictures of that. You can see it from a long ways away.
Lore here years ago was that North Dakota being the only place to have a base with 2 of the 3 tips of the nuclear triad would have been the 3rd most nuclear country in the world if we broke from the USA. I lived 2 miles from a launch site at one point so I would have had a front row seat to annihilation. Some time I want to go over to Cooperstown ND and visit an intact underground launch site that has been turned into a museum.
