I went to the first three quarters of the game and I went back in for the last field goal... Here were my non-game related observations.
Green out was unsuccessful, maybe 1 in 3 students wore green.
Weather didn't seem like much of a factor, but it was extremely cold and windy. It had to affect somehow. It did make fans leave early (myself), even in the tight game.
I didn't sit in student section, but it seemed like all the Hawk fans around me were pulling for ISU to win on the scoreboard, and they seemed disappointed when they didn't pull it out.
A Penn State fan sat in front of me and people were giving him a really hard time. One guy even slapped the top of his head nonchalantly as he was walking up the aisle... Some people are just idiots.
After the game, middle aged men were literally dancing and singing in the streets. It was embarassing.
Iowa will be feeding off this one for the next 2 years. Too bad for Hawkeye fans, this will just keep their staff around for another 1-2 years.
