"Directly at the 50 yardline"
Upper level, 50 yardline. Great view of both sides of the field and the videoboards. You're far from the field, but you can see absolutely everything.
The walk up the stairs to row 19 is a bit difficult and probably not recommended for kids or older adults. If you don't plan on going up and down the stairs a lot, these are pretty ideal for the 500 level.
Best for... watching the game
Avoid if... you're bringing the family
