lost treasure

I was flipping through my cellphone photos - about 98 of 122 picture are of my cat, am I an old, crazy woman? - and stumbled upon this classic. This the the parking garage near both the DCJCC and the Keegan Theatre in NW DC. You will, of course, stop because you figure it's some sort of parking area in which you aren't welcome.

Feel free to tell me who doesn't qualify to park here.
