Hide your guns, and get yourself a pork roll, egg, and cheese sandwich, and work on coping strategies for gridlock, crowding, and noise is my advice. Maybe you're one of the lucky ones who won't live in the NE Corridor and will have a nice place up in Sussex County or down in the Pine Barrens somewhere.
I actually kind of screwed myself over - my visceral disgust for the Garden State was so great that the only plan I made was leaving. Born there, finally got out when I was 26. Everyone says yankees don't get guns or people from the Northeast are just terrible, terrible when it comes to the Constitution.
I won't pretend that's the main reason I left, but it was sure one of the big ones on the checklist. The problem was, once I got out, I didn't know what to do with my life. The need to leave was so great I never considered that there was life afterward. I think I subconsciously assumed that everything beyond the Delaware was the Promised Land or something, where there'd be eternal bliss and that was it.
My advice is, seek out other enthusiasts through gun organizations and ranges but don't bring up guns and the fact that you own them or enjoy them with your neighbors or co-workers. Not everyone in NJ is anti-gun, but I found out long before I ever owned a gun (I refused to, in New Jersey) that civilian gun ownership is socially unacceptable in many circles -- you could be regarded as a psychopath, especially if you live in suburban developments. As I say, not everywhere is like this but I'd tread lightly.
A guy who worked for my company got in trouble for talking about his hunting rifles because it made people uncomfortable (because, you can't trust a man with a rifle! He might KEEL YOU!)
I know more than anyone that sometimes you just gotta live in New Jersey. Maybe you need a job badly, or maybe you have a kid there. I get it. But there are sacrifices, and tenacity is key.
But, eugh.
May God take pity upon you, and all the good people of the Garden State. On the other hand, if you can put up with living in New Jersey, probably you can put up with anything. It'll make you more of a man, that way. If you can avoid sobbing on the Parkway, that is.
