You see this happen at almost every game (college and pro) on TV. Even if people don't have to leave the stadium for a beer, they still struggle to make it back from halftime bathroom trips.Another candidate for ISU's worst tradition:
Leaving at halftime to chug a few beers and not getting back in time for the third quarter kickoff. It looks terrible when we're on TV and they do a pan of the stands before 2nd half kickoff with huge sections of empty stands in a game that is a sellout
