For those with the attendance superiority complex, you might want to take a look at ISU attendance from as recent as two years ago (CPR's second year). Particularly the last game where ISU was fighting #15 MU for bowl eligibility. The announced attendance was about 42,000, and by the looks on TV, There were probably about 35,000 actually in attendance. Was it cold? Certainly, but according to this thread, cold shouldn't matter.
And then the year before that, again with ISU fighting to get bowl-eligible, #18 OSU played in Ames to an announced crowd of about 40,000 (ESPN in town, nice fall day), and by the looks on TV, there were maybe 35,000 there (probably closer to 30,000). I believe the predominant excuse given on that occasion was that is was nice day so kids had to go home to combine corn (check the archive). To CF's credit, that excuse was called called into question.
We've had good home attendance for...well...1.5 years in a row now. If within the last five years, your school (of nearly 30,000 enrollment) has had to give "combining corn" as an excuse for a sparse crowd during a game when 1) the team is fighting for bowl eligibility, 2) a rated team is in town, 3) beautiful sunny, fall day, 4) ESPN is televising the game, you really have no business trashing other schools for bad attendance. It really makes you look silly...
