The attendance for the game with Iowa at Northern Iowa was only 6,480.
I don't know how much the weather might have had to do with that, but this game was a sellout 2 years ago at UNI (7,043), and they could have sold twice that many tickets. Usually these games are sold out well in advance.
4 years ago when they played at the UNI Dome, they drew 13,288, and previous games there have drawn over 14,000.
Last night's attendance of 6,480 probably represents the lack of interest by fans of Iowa since their home attendance is way down.
