The Joisey accent (which I happen to love) changes as you drive down the toinpike. And if you go west in Joisey, there is a New England/Upstate NY twang that sets in.
But God forbid you go for a drive and end up in the Catskills.
"Oy vey"!
As you go farther south into Salem, Cumberland, Atlantic and Cape May counties, the accent comes closer to the Ozarks than anywhere else.
