The only place that I know of like that isn't near an island. People say the same thing about this installation too, but what they do there is both
more prosaic and at the same time a really neat training facility, one of a kind.
*********** Army story time "This ain' t no sh-t..."
You never know. When I was a kid and too young to jine the real Army I worked for the Corps of Engineers. (they'll hire you at 14, part time)
I'd worked in the comm maintenance building for over a year, when one day while I was outside waiting for them to open up one morning, I finally
looked at the place. There were antennas all over the roof and surrounding area. I knew what SOME of them were, but a lot of them, it just
didn't make sense. We used a set of them for repair work. But what were all the others?
So I started walking around the building, really looking at it. There were oddball concrete pads, vent shafts, little concrete outbuildings with no
doors or accesses. So when the captain got there, I asked.
"Oh, you finally noticed. Not everyone does. As the most junior guy that noticed, you automatically get a new duty"
He led me into a room I didn't know was there, and there were stairs. Under the building...was another one. There was a full-on generation setup that
could run the entire base, a ton of stored food, tunnels all under the base, a warehouse full of unusual parts, and a secure comm setup that was used
in the event of a major attack on the US. There was a second function the base had, which wasn't apparent.
So little 16 yr old Tommy got to run the generators once a week, do the maintenance on them, and every quarter, I got to man the comm setup and answer
with our particular "code". Every base so equipped had a drill once a quarter where we called out our callsign and status code in turn. We were
about 10 down from Norad. I don't know what significance the order had.
Pure heaven for an Army brat. Even Dad didn't know that crap was under there.
This to say, it isn't always real obvious what's here and there.
