Do they allow people to park really early before a show? Let's say 5hrs before a 7pm show?

park near the porta potties

Park and drink beer. If you park at the back there's trees ie: bathrooms lol

Probably not five hours before. I'd say possibly two hours, there's always a lot of tailgating.

Yep, lots of people tailgate before concerts

Yes, they do allow tailgating before shows.

Depends on the show , you can always call and find out what time they open the gate. But usually they do and they do allow tailgating.

Yes they do
