It is very hot, so I would recommend you try to time it to where you get there about the time they open the dome, about 1:45 - 2:00.
Head for section 112 to 116. Despite being a scrimmage, there are plenty of good seats available. Parking is $10 in the lot, but try to get the closest one to the entrance. This year they are opening both the North and South entrance, I suggest using the south entrance, less people and you don't have to put your boys through the god awful smell of bat poop by using the north entrance.
I have to work at 2 tomorrow, or I would be there.
Enjoy and take good notes. Looking forward to your detailed report.
