Wanna see some medieval European architecture while you're in South Dakota? (If you don't answer "Um, yes?", then I don't know what to tell you.) Chapel in the Hills is a total gem. It's such a neat piece of history and in one of the most gorgeous settings imaginable. The little museum is neat too. And when we were there, the volunteer working in the gift shop was incredibly nice and funny. Just love this place. Five stars!
