I only go to 1 or 2 games a year, so pretty limited complaints, but here they are:
1. Getting in the stadium sucks donkey balls. At least it did during the TN game - they had everybody routed through, over and around everything they could find on the SW entrance. Just stupid. The stadium should have been built so that entrance and exiting is pretty streamlined, but it seems that was completely forgotten about.
2. Bugle Call - slows the game down, needs to be done prior to the game.
3. Acoustics just suck. We could barely hear anything in the south zone upper deck. Some of the announcements listed above that try to create an atmosphere just dont' - let the game get played.
4. Ribbon boards/jumbotron/advertisements - not every damned thing in the world needs to be sponsored or advertised at 6 million watts of light.
5. Traffic after the game, but that's expected and not much can really be done about it. Small town, lots of people in a concentrated area.
6. Games take way the hell too long. Between commercial breaks, advertising breaks, Joe Bob from Class of '61 cut his toenails today awards, reviews that take forever (should be a 1 minute time limit on these things - if it's not clear after 1 minute of review, call on the field stands) and whatever else just add a lot of unecessary time to the game. With the OT's in the TN game, it was something like 5 or 6 hours long. Or it felt that way. Play the game and quit drawing the time out with fluff and fodder.
This doesn't have anything to do with the atmosphere really, just a personal observation, but the redesign of the field with the stands nearly up on the field and very little area outside of the playing surface makes everything seem really crowded. I don't like that, wish we still had the track and a little bit of room around the playing surface so that the game and field itself was the main focus and not all of the other circus goings on.
