Born and raised in NJ. I fled at the first possible opportunity, and I may be a little biased.
I’m from the small part of the state that’s not actually in NJ. Culturally, my town at least is in Pennsylvania. It’s ten-twenty minutes from center city Philly, and very much a suburb of the city. We’re also the one part of NJ where if you say you’re going into “the city”, it’s Philly, not NYC. That said:
Camden is, indeed, currently the most dangerous city in the United States. I know from experience it is not a place where three teenage girls want to drive into and get horribly lost in at night. They’re trying really hard to revitalize it, so it’s got a teeny-tiny piece of waterfront with insanely expensive rents. The rest of it is very much a typical inner-city: gangs, violence, drugs, and a huge problem with AIDS.
A lot of north Jersey is, as said before, industrial and generally regarded as a sprawling industrial wasteland. I don’t know all that much about it, really.
The shore varies wildly, from wonderful, adorable little towns (Sea Isle City comes to mind), to the big Atlantic City, to some small towns that have really fallen past their prime. It’s also one of the few places possibly in the world where you need to pay for a ‘beach tag’, which gives you permission to sit on the beach. Island Beach State Park is, indeed, a state park and doesn’t require beach tags, but you need to pay a fee to get in.
The Pine Barrens can be really nice, in fact. My school district, every year, sends the sixth-graders for a week-long wilderness education retreat thing, at a place called - ready? - Mt. Misery. It’s actually a great place. Some decent hiking trails and whatnot, but there are a ton of deer ticks. My mother once got Lyme disease from hiking there (she wanted to go for her mothers day gift, too!)
Then, there’s the rest of the state. It can be summed up thusly: 4 nuclear power plants, the first indoor shopping mall on the east coast, lots of other malls, even more strip malls, suburban sprawl, the Turnpike, the Expressway, toll-booths, toxic waste dumps, at least one rodeo, bizarre laws about left-turns and gas stations, and some of the least friendly people in the country.
And, diners, and out in the 'boonies, roadside produce stands where you can get the best tomatoes, ever.
