An interesting observation. I live in the Hill Country of Texas and the number of people moving into this area seem to be predominantly from the North, in general, and from the North East specifically. Now, don;t ask where I got that from, my thought springs from what I see every Sunday at my church. I know, it's not scientific but it is what I see.
I am a damned yankee by birth, a redneck good ole boy by osmosis. NC in winter, PA in summer.
