The home-and-home worthy teams in that circle (excluding Indiana and Ohio because they're too far away and your Ohio bias is showing :realmad:
Creighton
Nebraska
Mizzou
St. Louis
Illinois
Northwestern
Marquette
Wisconsin
Minnesota
I think Clone fans would make a day out of a trip to any of these locations, if the game was on a weekend without ISU football.
Ohio State is 10 hours from Ames. They are consistently a top 15 team with Thad as the coach. It would be a great matchup every year.
I would also include Notre Dame and Purdue unless you're cutting out the whole state of Indiana completely.
