The South has more pasty fatsos than any other part of the country. If by Jersey girls, you mean those idiots from Staten Island and Brooklyn (like those idiots on a certain TV show, all from New York) who dominate the shore in the summer, I guess you are right. Thanks to the ethnic/racial diversity, you do find alot of hotties in NY/NJ, along with some plain jane types. You don't start seeing fat, tattooed whitegirls until you get west of the Delaware River (PA). You can't say the same for certain other regions of the country.
In terms of attractiveness, I would say that the only two states in the south that have modestly attractive women are (southern) Louisiana and Texas.
