I thought the photo of a couple of us on top of the Art Museum steps last year was a nice shot with the Philly skyline in the background ...no, not that kind of Skyline

I'd link to the shot but Mr. rizing phoenix mike musta let his account go dead cause those pics are all redX's now.
Maybe with the Dali exhibit going on, they'll either not have room for a bunch of Supras or think it's just surreal enough for Dali. If any body is interested in this idea, and the parking lot attendant isn't as cooperative as last year, maybe try the free lot at the back of the Art Museum down level with East River Dr. or whatever it's named now. And there's always Belmont Plateau but that could be crowded if some kind of ballgame or huge picnic is going on.
Keep in mind that on weekends, the West River Dr. is closed from Montgomery Dr. to the ...Sweetbriar cutoff, I think that's what that street is called.
