No lie - I had a contractor once who did DC. He did some work at Raven Rock. Know how you get into Raven Rock? You drive to the official unofficial guarded gate out in the middle of nowhere for some reason, they sweep your car, they pat you down, they make a big bit of security theater, and then they tell you to turn around, drive down the road a quarter mile and turn left up the dirt road.
et viola. Raven Rock.
