It seems a bit crazy to me that this game isn't sold out for you guys. Over the years I have lived in San Diego, LA, San Fran, Portland, Honolulu, Anchorage, and now Houston and have seen a pretty big fan presence for you folks everywhere I go. There is the support, so it is surprising to me with your start it isn't sold out. Different world today though.
As the season goes on, the more I am agreeing with the poster in a previous thread who laid out the obvious: Iowan's don't make week/week decisions, in general. When they dumped their season tickets, they made that decision and stuck with it, not changing their weekly plans. It isn't that they are still upset/boycotting, just that their plans have been changed, their thought process altered. That may change next year. The perfect example was 2002. The team was 9-1, ranked, and playing Northwestern and didn't sell out. That next year they sold out (after the 2 beginning chumps), because the people made their plans to attend (the Big Ten at least).
Now why is this game nearing sellout? Its homecoming, people had plans to attend this game regardless of 5-0, but the record obviously helps.
We are a schedule-oriented folk up here.
