[9megameter]

Currently I live in PA and work in NJ, meaning I cross state lines every morning to go to work. Every now and then I do get the urge to go the range, usually after working hours. To make a long story short the most convenient thing to do in this case would be to bring my pistol with me, and keep it in the car.

Putting aside for the moment the question of bringing a gun to work and leaving it in the car (which has been addressed elsewhere), can anyone tell me about the legality of taking a gun registered in PA across state lines into NJ? The gun in question is locked and unloaded, if that makes any difference at all.
