The Professor is right. There appears to be some confusion about just what the Midwest constitutes.
Citizens of Earth, let me clear it up for you.
Ohio, Indiana, Illinois, Michigan, Wisconsin, Minnesota, Iowa, Missouri, Kansas*
States Which May Share Our Culture, But Are Not, In Fact, Midwest, Mostly Because the Midwest DOES NOT Have Mountain Ranges
Arkansas, Kentucky, Pennsylvania (but really, only the western part)
The State We’ll Take Because It Has to Go Someplace, but Damn It, Now You’re Stretching It
