Not that I would know, but the potato guns rock! Be careful though, 'cuz here in AZ they are considered a "firearm" as the projectile is expelled by expanding gasses.
Doesn't matter here, hell me and a friend got pulled over by some cops because we were wrongly suspected in trespassing or something during deer season, there were two shotguns and two rifles in the truck, I was holding one, open boxes of shells on the dash (we just got back in from the woods) and the policeman didn't care. Neither of us were even 18 (supposedly lowest age to be legally able to carry guns in cars.) Wow its great to live in Ga. And did you know if you are over 18 and driving a pickup, you don't have to wear a seatbelt here? haha
