When I first came to the Washington DC area I taught at a school that is right around the corner from the headquarters of the Central Intelligence Agency. It’s location was a secret. There were no road signs pointing to it and the maps showed only a Department of Transportation testing facility. But everyone in the neighborhood knew exactly what it was and where it was.
A few years later the Agency gave up the charade and actually put up signs on the main road pointing drivers right to the main gate of "Headquarters – Central Intelligence". This weekend, I happened to drive down that road again after many years. The signs at the turn to the entrance now point to a facility called "The George Bush Center for Intelligence".
