I am doing a bit of historical research. I am told there was an underground facility near Traer for AT&T and their old coaxial cable long distance system, called L-4.

This would have an entry building about 10X10, a set of exhaust stacks, and a set of coffin type doors for the escape hatch.

Anyone know of such a thing near Traer?
