Who said anything about big stores? Every big city I have lived in has had a stadium and parking lots owned by either the stadium or third parties which allow tailgating and I have been to/was involved in a good many events held in private parking lots. Big stores open 7 days a week if not 24 hours a day are obviously not going to sacrifice their parking lots but a good number of parking lots are mostly vacant on the weekends, they serve the 5 days a week, 9-5 buisness world and they are more willing to sacrifice their mostly empty weekend lots.

So not the city, the stadium corporation (which might have ties to the city, but usually a wholly separate organization) or private third parties. Like I said.

Once again I've had a lot of very mixed experiences on this one. Some don't care, some see it as an insurance liability. I've spent a lot of my life adjacent to commerical property management, I can't imagine most of these groups being thoroughly OK with unknown groups using their lots for whatever. Seems like a good chance to get sued.
