My sister's back from her mission trip. She's brought back a slight Wisconsin accent with her. Weirdly enough, the trip was to North Carolina. She blames it on the Wisconsins surrounding her - apparently two thirds of the mission group was made up of Wisconsins.
It's kind of hilarious. Examples are hard to reproduce here, but one of my favorites was when an exclamation of "No!" was more like "Nohh!"
On a semi related note: Wisconsins? Wisconsans? Wisconsinans?
