Curious, but when I worked at the Pentagon, I was assigned to Fort Detrick. Always made us nervous to just go there for paper work or something as we all knew what was there.
I sort of know what you mean. I did some work at Whiteman AFB years ago, and while I never actually went into the silos, just knowing what was buried not that far away was rather eerie. And then seeing the launch scenes in the movie "The Day After" gave me a really uncomfortable feeling in the pit of my stomach.
