I was sitting next to a lone UMASS fan on the BYU sideline.  He was awesome.  He told me he bought tickets on the Visitor side because he didn't think there would be that many BYU fans at the game.  He was very impressed with our showing.  Also, when BYU scored you could see a lot of fans singing the fight song on the UMASS side of the field.  I would put it 65-70% BYU fans.  Great atmosphere once the Cougars started scoring.  I will probably go the game in Amherst MA next year.
