No offense but asking police for gun law information is a waste of time since 95% of them have no idea what they are. They just enforce what they THINK it should be and let the DA sort it out. Of couse that usually ends up with your gun impounded for months while the DA tries to find ANYTHING that will stick... If you ever get your gun back.
To the guy in NJ... You need to find a range in state, you can't legally take a handgun to NY to shoot. Your saving grace here is cops don't usually sit around gun shops checking permits
To the original poster, I BELIEVE it is legal to take a handgun to a FEDERAL park now. So if your camping in a federal park you may be ok, but state or private property is a no no.
