Oregon might be a college town. Not sure - never been. The other three are for sure not college towns.
Penn State
Michigan
Indiana
Purdue
Illinois
Iowa
Those truly feel like college towns. Madison, Nebraska and MSU have a college feel, but maybe are not college towns. No pro teams.
Ohio State
Northwestern
Minnesota
Definitely not college towns. Pro teams.
I've not been to Rutgers or Maryland. Can't make an opinion on those two.
