I agree that the stadium experience could be so much better. Cut the ad blitzkrieg. Use the ribbons to show stats, tweets, etc. Show the video board to show photos from instagram, facebook, and twitter with a particular hashtag (#byufootball, for example). Get Wifi up and running. I'll keep traveling to Provo for one game per year because it's an awesome tradition with my son but they really need to work on the stadium experience if they want to keep selling out.
P.S. popcorn popping should be banned. It's just embarrassing.
