One of the classic stadium destinations in college football.
Since I was here for an event, not a game, I can't really comment on the sightlines or seating. However, it is one of the few recognizable sights: situated between two mountains, panoramic shots of the stadium will be frequently shown on TV and the stadium is easily visible entering Phoenix airspace. Since it's only a few miles from the airport, you get a nice close-up on approach.
Although they have apparent pay lots, event parking here was free which I greatly appreciated. As a bonus, there are a few different ways in and out of the area, so there wasn't much of a traffic jam after the event.
