Although Dave asserts that the Toms River is in "Central NJ", you must remember the cardinal law of location within NJ: (Homativity..related to relativity but dealing with the principle of perceived geographical reference based on distance from your nj postal location...of course having nothing to do with the term "going postal" all word-associations aside). No matter where I live in NJ, 10 miles or more "north" of me is "North Jersey" and 10 miles or more "south" of me is "South Jersey". There are some corollaries to this law: Shoretivity - which is if I live in "North Jersey" then any point South of the Raritan River is considered "The Shore". (Just for the readers reference, although completely tangential to this discussion is the concept of Philadelphity...of course being the annexation of NJ West of I295 to metro Philadelphia.)
Now, given the population densities, and recalling the Clintonian principle of popularity-makes-it-truth, then obviously Toms River is simultaneously in "South Jersey" and at "The Shore".
QED.
