The area between the Aquatic Center and Clippinger is nice. Lots of shade and grass, and you get some pre-pre-game entertainment from the 110, which will assemble there before heading over to the stadium. You can't pull a vehicle in (unless you have an orange lot pass and snag one next to the area, or can get there early and grab a spot right behind Clippinger), but it works fine if you have a pop-up or canopy.
So anyone can just pop up a canopy there? You don't have to have a pass or anything? Thanks for your responses.
The OUPD/APD/Sheriff's Dept assemble next to Walter Hall, so if it was against the rules there are plenty of law enforcement officers there to shut it down. I've been tailgating over there for 3 years or so, and I've never seen them kick someone out for it, so I'd take it as a good sign that it's OK. Closing down South Green Drive right there too would be a signal to me that they want people coming to the stadium from that area.
