Been to "the fort" twice, once on 'official business', once on a joyride around the 'campus'. :-) ("See them big sat dishes? Don't want to get too close to them, marines with guns up there.") The visitor's center has a small, but facinating museum of crypto stuff, everything from enigma-style machines to a device that does I-don't-remember-how-many-but-it-was-huge gigaflops on a hand-rolled chip made on site, to a device for intercepting (and decrypting) microwave transmissions. Not much satilite stuff. Pretty cool. The guards all wear big (loaded, I checked) guns. You're issued a little badge to carry around your neck. Get too far from your escort, or in a room without your escort, and they get really upset (from what I was told, I didn't try). Across the highway is a state camp for delinquent boys. Jim
