Didn’t news about this place leak out back around 1990? Maybe I’m thinking of the Greenbrier Hotel in WV.
Yeah, that was the Greenbrier Hotel.
Yes, I was thinking of the Greenbrier and the underground tunnel complex at Denver International Airport.
I believe the Greenbrier complex was sold off a few years ago.
There are NUMEROUS locations I know of, on the eastern seaboard, that fit the description of this place...I’ve seen a couple. The range from the “sixth sub basement of new government installations”, to reporposed salt mines. They are self contained, self sufficient, subterrainian, and generally VERY posh. I’ll assume there are many more that I’ve never seen nor heard of.
