I lived in South Dakota for a year out of school. The two are more or less the same state. Very flat, very boring, very few people, super conservative. Moving there from undergrad at Wisconsin was quite a culture shock and I struggled to adapt socially (although being a reporter with a shift that ended after midnight including ALL Friday nights didn't help). Some people actually DO find that appealing. I did not.
I know nothing about the law school itself, though.
