Different than what's in a city, and generally not as enjoyable if you're just passively consuming it. Lots of motorsport (auto manufacturing was huge in the area, very long tradition of it), fishing/hunting, local music (some styles represented better than others, but that goes for everywhere), hobbyist heavy industry. There's definitely plenty of other stuff going on that I just haven't heard about. Pretty often I run into situations where I'm talking to somebody about a new interest and they say "yeah, there's actually plenty of that going on, look into/talk to X, Y, or Z". Not so much culinary or visual/fine arts stuff happening, so if you're looking to participate/collaborate as far as that goes, I can tell you off the top of my head that the area would be a bad fit.
If you're looking to be involved in culture for just a few hours at a time by going to a restaurant or show and not being involved much past that, you're going to be painfully bored here. I don't think doing that is a moral shortcoming or anything like that, but there are a lot of people that are doing that, don't realize it, and misinterpret the lack of opportunities to do so outside of a large city as that place just not having any culture at all.
