Me and couple buddies of mine want to head out to el centro in a few weeks and shoot some trap. The thing is, the shotguns are all my dad's. He has a 10, 12 and 20, all of them registered. My question is if I run into a cop or fish & game (I think there are more game wardens in El centro than cops lol), will they ask for anything? I don't have any sort of special operating licenses or anything. I am over 18 as are my friends. I assume since I can buy the ammunition for it, I can use the guns but I want to be sure. I don't want to get stuck in the middle of the desert for anything illegal. I read some of the PDFs on the bureau of firearms website and it is confusing as hell.

I also am taking a couple .22s for some target shooting, I don't know if this matters either...

Thanks
