Speaking of Valerie Plame...how well hidden is the parking lot for CIA employees at Langley? It raises an interesting question. The CIA's parking lots are access controlled. I have to assume that they use a decal and maybe an electronic device to permit access. I can't imagine that each and every car has to stop and be individually checked in when they arrive in the morning or other shift changes. Did Plame's car have a CIA decal before she was "outed" by Novak? Even if it didn't say CIA anyone who knew someone at the CIA and had seen their CIA decal would recognize the decal on someone else's car. If they came out as a former CIA NOC to talk on TV, etc the people who knew them before would/could remember the decals on their car.

I would guess that covert agents at least would not have decals which are permanently affixed to a window or bumper, but agents might have decals that hang from the rear-view mirror (and can be hidden in the glove compartment at other times) or maybe a credit-card-sized card or perhaps something like a garage-door opener to permit access to the lot.
