I really don't get most of these divisions.
How does suburban NJ sound like Buffalo or Rochester?
Even stranger, are they really saying NJ sounds like MI?? That's insane.
And how does Westchester County, NY sound different from suburban Long Island? It's very similar demographics with similar origins. They sound the same, except that Westchester is a little WASPier and has more corporate relocatee types, so more flat American accents, but MOST people in either area sound about the same.
