Watch Out!
National forests are OK for open carry, IF you don't shoot within 100 yards of any road, don't shoot any trees, don't carry in a car for any reason (unless you have CCW) and don't have bay area mountain bikers call the NSF on you.
Here's the story:
rant:
My two brothers and I drive 3 hours into the forest to camp and target shoot. It's 9am in the morning and we are shooting. 9:30am, the NSF agent shows up stating "some mountain bikers reported that you were blasting away with fully automatic weapons". NSF agent notices our targets which were leaning against a dead tree. "It's destruction of national property to shoot at a living tree. That tree still has branches attached so it must be alive" (Yes it had branches which were dried and cracked when broken. no greenery anywhere = dead tree). "Also, you are within 100 yards of that road" (It was a dirt 4x4 trail that was a good mile off the NSF fire road) "It's illegal to own fully automatic weapons in this state. How many do you have? Bring them here for inspection" She then inspected our sks, saiga, xd9mm and S&W 357... She noticed some trash about 50 yards away from our camp. "it's illegal to dump trash on NF land"
Long story short, we did nothing wrong. We were well away from a real road, only shot at a dead tree, picked up all our trash and frankly we left the camp site far better than when we first got there. What did we get for being such good campers? A 2 hour lecture from the NSF agent who didn't know that a sks is semi-automatic, we had to pick up trash that had probly been there for years and we were told to leave. (the worst part was having someone who doesn't know the difference between full-auto and semi-auto inspect my guns. they got a thourough cleaning...) The only good thing was that we weren't fined for $2k, which she had threatened. My brothers have a magic gift of BSing their way out of sticky situations, It's something I'll always be envious of
I hope this story will get one point through: Yes it's legal to open carry, but cover your ass and don't CCW in a car unless you have a permit. Don't shoot anywhere near a tree, and don't bring targets with you or you will be blamed for any trash found within 100 yards of your camp.
