State Department / CIA communications facility

The Beltsville Agricultural Research Center is world famous for the study
of insects, but more than one kind of bug is grown at this location. The
site has also been used as a base for spies and diplomats since the late
70's as a major communications center, and a wet-house where bugs of a
more electronic nature are nurtured. In a forested area near Rt 295 there
are two sister building set back from the road.
