so you've been to Cumberland county I see....

Agreed to a point there Jake. I think that central jersey is more densely populated if you look from Shore area to Trenton. Not a lot of farm land in this area, not a lot of open land.
Noth jersey is mostly concentrated near the city, but westward by Island, its treeland.

In my map with the colors, the green part is trees and open land, blue is city or city-ish type atmosphere, and the tan part is shore area.
