I live in Iowa. No, really, don't hang up. It wasn't my first choice, but oh well. It's pretty cool how much NFL diversity there is here. Most local newspapers will cover the local team, e.g., The Chicago Tribune spends a lot of time on the Bears, etc. Here, the news covers the Bears, Vikings, Packers, Chiefs, and Rams. It seems like there are few Broncos fans, too. And of course there are always Cowboys, Steelers, and Raiders fans everywhere. Depending on who's doing well, you'll see more of one team's supporters over another. Overall, I'd say it goes Vikings, Bears, Chiefs, Packers, Rams here in Des Moines, but that's just anecdotal. They did a survey on this subject a few years ago, but I don't remember the results and I don't feel like looking it up at 12:30 AM. Of course, there are more Vikings fans in the north, Chiefs fans in the south, and Bears and Packers fans in the east.
College footbal is big for a lot of people, but I couldn't care less about the stupid Hawkeyes or Cyclones (I'm originally from IL). I think of college football as the NFL's minor leagues.
