A classic debate.. I’d say Central NJ and here’s why. Take the Garden State Parkway as your measurement, since it goes from Cape May all the way up to the NY line and covers the entire state top to bottom. The GSP has 173 exits I believe, exit 1 being Cape May and 173 being the last exit before NY, and divide that by 3 to determine SNJ, CNJ and NNJ, then SNJ is exits 1-58, CNJ is 59-115, NNJ is 116-173. Push those boundaries all the way east and west of NJ and that’s your determination. Unless you can think of a better way to determine it in equal parts, that’s how I feel it should be considered.
