"Almost the Farthest Seats in the Stadium"
When you get to the 400 level, make sure you purchase all nine of your beers, all six of your hot dogs and all twelve of your churros before getting to your seats. You will not want to come back down the stairs after going up once. But good luck carrying all that stuff up, and good luck figuring out a bathroom plan.
Seriously, the person in front of me carrying two beers stopped at row 11 for what he called a "breather". I'm not sure how you can safely navigate the stairs with beers in both hands and not being able to use the handrail. If you have bad knees, go to the bathroom frequently or get vertigo from time to time, stick with a lower row where you won't have to climb Everest to get to your seats.
Forgetting the hike, I actually liked the view from these seats. The whole field is visible and it's actually kind of quiet and peaceful near the top of such a large stadium. You can literally look down on everyone and everything that's going on.
Best for... fans on a budget
Avoid if... you're bringing the family, you consider yourself "Big" and "Tall"
