I get it, you've had season tickets since the Jim Walden era so you don't care.
For the rest of us peasants we do stuff like idk......use the bathroom once inside, grab some food or water, make our way to the seats.....sometimes it can take 5-10minutes depending on location, find our seats, maybe interact and make some friends with people around us, watch pre-game warm-ups, watch the band and cheerleaders........just generally enjoy the ambience of being at a football game.
It wasn't even that hot yesterday. The temp was about 92 with a heat index of 93. A simple tip, take a kitchen towel, wet it down and put it around your neck. It will cool anywhere from 30-60 minutes depending on some other factors. Wrapping it in ice and then getting it wet works even better.
