220 feet below ground..that's 22 stories!.........limestone walls are painted brilliant white, bright lights illuminate the passages ........50 degree water from 150-acre underground lake....Fifteen colossal generators....125 large vaults, (One vault is the size of a shopping center) plus another 25 smaller units and hundreds of acres still to be developed...trouble is..armed guards, steel gates, layers of security, biometrics but it's protected from the elements, civil unrest, terrorist-type things>
