At the following link is a NY TImes (boo) dialect quiz that identifies where you grew up. 25 questions about certain phrases and how you pronounce certain words is all it takes. The results names the CITIES that are most similar to your answers. So for me it was Lexington, Louisville and someplace in Arkansas. It didn't name Paducah because it is too small, but the heat map was fascinating. The reddest part of the map was the JP and areas along the Mississippi and Ohio rivers.
Got my daughters by naming Denver, but the city part of the answer came into play for my wife. Even though the part of Ohio where she grew up was very red, the cities named were Sacramento and Fresno.
