If you are in the BYU section, you can go there and be more or less insulated from the trash. Just watch your step, because that's on the west side.
North end zone is where adults drink and take off their shirts.
East side is where the student section is. I hear the kids smell and they are always lifting up their signage and flags so it's harder to see the field over there.
Regardless of where you are, expect to hear derogatory comments about Mormons. Sticks and stones.
