They are in southeast Wyoming, western Nebraska and northeast Colorado.
Basically they are all within 100 miles of Cheyenne (F.E. Warren AFB).

My favorite one is about 25 miles NE of Cheyenne on highway 85.

(and I'm sure that reference to Warren will get this post read by the gov't)

Originally those cabinets were pressurized with nitrogen to minimize
oxidation of the relay contacts, hence the gasketed doors.

Probably not practical unless you are local though :-)
