Are you going to Train Wreck Distillery? Ive been there a bunch of times, its a pretty great place and the area is pretty nice. The brew scene is really hot right now in this area, and I am loving it. I wouldnt venture down into the Camden County area (Cherry Hill and the like). Its much cheaper, housing and property tax wise, the traffic is not nearly as bad, and its less crowded in the Burlington County area. If you are working in Mt Holly, I dont think there is a need for you to live out in PA, it just seems like a waste and a hassle in commuting, plus your are just going to be in even MORE of a suburb of Philly, across the river from where you work, which will make finding a place to live harder and more expensive. For a while I lived in PA and worked in NJ, it was not worth it, whatever I saved on taxes was quickly lost on every other cost/service/fee/toll/permit/ect. The cost of living is more than just your property taxes. If you want more space, head out the other direction toward Pemberton NJ, lower housing taxes and more space are. If you want to be closer to the metro, head to the small NJ towns along the river and the train (riverline) such as Palmyra, Riverside, Riverton, Delran, Cinnaminson. They are nice places at decent prices, some nice downtowns, and that train is a cheap and easy zip into the city. Living along the patco is another option, but to me that area of Camden county is nothing but generic suburbs. Within the general area though, your a short drive to the beach, delaware water gap, poconos, pinelands, basically a host of mountain/flatland/lake/shore/river/ocean outdoor activies, while also being a reasonable distance from Philly (duh), NYC, DC and other fun metros.
On the car side, its pretty great. I am at NJMP about once a month (will actually be there Wednesday for TNiA), and within a few hours theres; Pocono, Pitt, Summit Point, Dover, NJMP, Mid Ohio, Watkins Glen, VIR, NYST, Palmer, Thompson, Lime Rock, NHMS, Nelson Ledges, Dominion, Monticello, and whatever I might have forgotten... Plus active autocross in SJSCCA and Philly SCCA, reasonably close rallycross. Atco dragway is still active as is Cecil County dragway. The car scene is actually really big and diverse in NJ.
Since I am right down the road from Mt Holly, if you want to meet up after your interview send me a PM and I will give you my number and we can talk all there is about living in NJ. Its not nearly as bad as all the haters make it out to be. Its easier than trying to put it all in a post.
