I've only driven through MO a few times, coming in to Joplin & usually yanking I-40 to St Louis, or staying south central to Branson. I see a lot of Confederate flag Southern style culture in quite a few areas of the state - which is quite pretty (I enjoy driving there). I did run into some wineries & orchards up around Rolla, which I'm told is pronounced Rawl-uh not Roll-uh, and asked how they came to be. The lady said she didn't know but heard that the Italians who settled in the area said it looked the most like home & planted grapes.
