It's an erroneous statement that Iowa fans travel well to Minnesota...they all live in Minneapolis. So unless you consider driving from Blaine to be traveling well, than it's just a false statement. Why would you want to stay in Iowa post-graduation anyway?
More, if they did travel from Iowa, it's because they are die-hards...not by choice but because of a complete lack of any other options. What else are they going to be fans of, the Barnstormers in AFL? Please, there is nothing to do in that lowly state, so they become Hawkeye fans by force, rather than by choice.
There is no doubt that Iowa is well-represented at Gopher v. Hawkeye games, but it is undoubtedly because they live in the Twin Cities and/or have nothing better to do in Iowa...just a fact.
