I did a search on College Board for you. i picked a random zipcode from Minneapolis and searched an area less then 100 miles from it. i found only one college: Minnesota State University, Mankato
Well there is the U, but I don't know anything first hand. Agsberg College is pretty nice. Small but has a nice theater department. Great people. I was accepted to their department as an actor. Did a couple of workshops as part of the application procces. I never didn't end up picking thier school, but I have worked with some people who did. I would reccoment taking a look at what they've got. It just wasn't the right feel for me.
