yes, park staffers are familiar with park rules, but not with national forest rules. For the national forests outside of national parks, shooting is allowed with some restrictions. Pittman-Robertson act demands it, and that's the national act which governs the taxation of firearms and ammmo, archery, fishing gear, and a few other items. If you're in a national park,(now)you can carry concealed with your permit, but no hunting/shooting. I wonder though, in CA, which refuses to honor any other state's ccp, Yosemite may still be required to honor your permit.
