Fifty states, fifty jurisdictions.

You can own and purchase guns in all 50 states. But the laws governing the use and transportation of guns (for instance, what constitutes "concealed carrying", for which you need a permit) vary from state to state.

I'm also not clear whether the Customs regs would require that someone crossing the border with a gun would have to declare it. I suspect that declaration would be required.

I have a recipe for squirrel. It might work for gophers, but you hafta be mighty careful with those little critters to only blow their heads off. Not much meat on 'em. And of course, you wouldn't have the beautiful tail garnish that you get with squirrel. ;)

Happy hunting!
