I taught last year at a small town in southern Michigan, near the Ohio border. For the last 12 years, I have been living in northern Michigan and I had to adopt to the culture of "the south." We cheer for Green Bay in the north, they cheer for Cleveland Browns in the south (who really cheers for the Lions anymore?). I was very surprised that in this rural area, they HAD school on the opening day of deer season. No one up north goes to school on the opening day of deer season!!! Whaddaya mean you don't drive snow machines to school? Tip-up, it's an ice-fishing thing.
Finally, one student got fed up and said, "We're not the crazy Yooper schools you were at before!" After that, I was always referred to as the "crazy Yooper teacher." This was not helped when I confirmed that there was indeed a university with the initials FU ... Finlandia University. Another student wore a t-shirt to school and everyone (incl. admin.) thought it was made up. I had to explain that it wasn't.
Boy did I have fun when explaining dialects, I got to speak all class as a "Yooper"
