I grew up a hawk, went to tISU for the engineering program, loved it. ISU has a lot of rural/small town kids that had similar backgrounds to me. My impression of the UofI is that it is a bunch of surburban Chicago kids that are wanna be doctors or lawyers that will eventually fail and become male nurses, bank tellers or government bureaucrats.
I tend to find two types of hawkeye fans when relating to ISU:
1. Iowan: They are happy to see ISU win as long as it isn't against the Hawks and would like to watch the Cyclones if they're on TV.
2. Hawkeye-D-bag: They hate ISU, call ISU alums f'ing farmers, root against ISU even when they play Nebby, and generally have no respect
Fortunately there are more Iowans than D-bags..
These are your internet (mainly) fans.
