I'm a close friend of a season ticket holder that sits here in section 111 for 8 games per season. I've accompanied him to a few games, never for a game against a divisional rival though. Almost all of the seats here in 111 sit especially close to the field since there is no tunnel in this corner of the stadium like there are in the other corners. Very clear unobstructed view, wish they were my seats. Only con is having one scoreboard to look at unless you want to turn around and look up to see the other two.
I've sat on the upper level as well and the view is still pretty good but nothing beats sitting those close to America's favorite game.

111 is great section in the corner of the endzone. One of the loudest and proudest in the stadium. You will love sitting here. Expect to pay $120+ for a ticket in this section. I have sat here numerous times. Not really a bad seat in this place.
