Minnesota offers inexpensive in-state tuition to anyone who attends Bemidji State in Bemidji or Southwest State University in Marshall. Bemidji is beautiful. If you like outdoorsy stuff and don't mind cold and snow, the campus, which is right on Lake Bemidji, is pretty nice. Tuition less than $6000 per year and room and board less than $5000 per year no matter where you are from.
