I'm sorry again that this is no help to the original post, but this thread reminds me how GREAT parking was at the Orange Bowl.!
Not talking about actual parking lots at the OB but the surrounding residential neighborhood. You'd just pay a homeowner a few bucks to park in his driveway.
Then when the game was over there was a grid of streets, rather than bottlenecked parking lot exits, for the traffic to disperse.
I don't imagine that system exists anymore...anywhere.
