Park Reg
I am not a lawyer, but you would be breaking a park regulation, kind of like drinking at campsites where they don't allow alcohol, shooting fireworks, or being like an 18yr old raising cane late at night with a group of buddies. I would bring a handgun and carry it discreetly if you feel the need for protection. I would not use it unless i absolutely had to for protection, not for nailing hogs. Do not tell anyone you have it and also carry a gun that you have a lot of money in, or high sentimental value (handed down from grandpa). You'd probably get slapped with a traffic ticket type fine and your gun maybe taken, but i don't think it would be the end of the world as in going to jail for a night like DWI/DUI. People whine that they you are a felon for carrying in a national park and that is completely false....again a park reg is nothing but at very worst comparable to a low level misdemeanor. Jaywalking, speeding 4 miles over, and not using a turn signal are about the same thing that i wouldn't lose sleep over. I wouldn't worry too much about the silly park regs keeping me from carrying a small handgun for protection either. I value my life much more than a slap on the wrist.
