I never have figured out how to categorize Oklahoma, but Midwest has never been on my Oklahoma bingo card. It's more like a less affluent extension of Texas that is full of bogus slot machines and smells like weed everywhere.

There is some surprisingly pretty land up there though. Growing up I always thought of it as a barren dust bowl wasteland. Lots and lots of trees in reality, at least in the eastern half. Don't know what's in the panhandle. I'm not sure anybody does.

Edit: Just as I finished typing this, a commercial came on the TV. To quote, and no I'm not kidding, "Live the flyover life. Move to Oklahoma."
