Kind of ironic that someone from CA cant find a way to bring guns into NJ legally. You would think it would be the other way around. In my opinion, I think the easiest solution would be to go to a range where you can rent a gun, or just use your fathers at Ft Dix.... What a shame.
I recently went to Philly for a bachelor party and the first destination was the Delaware Valley Sports Club. Since I was staying over I didn't bother bringing my guns. But my friend decided he wanted to. This meant he had to drive down and go directly home after missing the later festivities. The range was awesome they let us rent an AK and a Desert Eagle, a couple other pistols with no supervision and everyone had a great time. I recommend that range if anyone is in Philly.
