I'm up in Union at times (my collection is always here obviously), not South Jersey by any means and barely even central (seems you're okay with going to Pinfest though so same distance! ) but there's a lot of EM collectors up North here, I imagine there would be down there too due to all of the beaches, boardwalks, and their pasts.
You should go to one of Vic Camp's "open houses" sometime, his collection is beautiful and a very knowledgeable guy, with friends who also share those traits.
