Good to see you making out to yellow, man!
The first thing you have to ask is if you want to party on grass or on pavement. The grass is slightly further from the practice bubble, but it's obviously not as hot (if that is an issue Sunday), and it's nice on the feet.
From the Main St. entrance, stay left if you want to go to the grass, and right if you want to park on the pavement closest to the bubble.
I think most of us in the forum park in the grass, FWIW.
Porta potties are everywhere, so that shouldn't be a concern.
