You can take the Wisconsin boy out of Wisconsin but you can’t take Wisconsin out of the boy. This New York Times dialect quiz guesses which part of the country you’re from based on your preferences for certain words (e.g. “sneakers” vs. “tennis shoes” or “dinner” vs. “supper”).
It correctly shows I’m from the Midwest, but I think it gave too much credit to my answer on what you call the night before Halloween (I said “Devil’s Night”, which is only used in the Detroit area, and I know it only from watching the news. Other parts of the country have no word for that night).
