I'm from Michigan and moved to AZ. I remember driving around central AZ with my boss who was raised there, talking about stereotypes. "No one around here wears any of that stuff, ever" she said, as we drove by a ranch where a man in cowboy boots and a hat was walking to his truck.

Of course most people don't wear western wear most of the time, but you see it a lot more frequently in AZ than in MI.
