My point for posting that was that although Iowa fans find it hard to believe, there has been a steady increase of alumni and Iowa state fans in general popping up in the last 5 years or so, all over the upper midwest but especially in Iowa and Minnesota. I'd venture to guess that most of the posters who scoffed at the idea of DSM being anywhere close to 50/50 live on the eastern side of the state. As someone said earlier in the thread, Ross Peterson says as much, and hes not one to just give compliments to ISU so there is some merit there imo.
I wouldn't be surprised if it is 50/50 or even if it was still majority Iowa, but there is no denying the increase of ISU fans and it doesn't look like it's stopping any time soon.
