I think I've said this before but when I first started backpacking I carried a .45 auto. Then over time I went down to a 9mm. Then after I had gone like 15 years I switched to a 6" barrel Charter Arms Pathfinder in .22 mag. Finally after a particularly tough trip, overloaded I got a NAA mini master .22 mag.
As I have gone on and on the gun keeps getting smaller and smaller because I see it's not needed. Haven't brought myself to not bring it at all yet though.
Although that's only on long trips way back. Hardly ever have one car camping or hiking in my woods.
Seems like car camping is when you'd most want protection. Last summer there were a string of robberies along the Columbia River where the authorities believed the same guy would stop where people were camping in fairly out of the way sites and rob them.
I always carry in the woods, and usually around town. Only one time have I actually had my gun in hand, though didn't use it. I was about 22 at the time, and my mom and I got tired of being in my grandparents stuffy house and decided to go for a walk. Now, my grandparents lived way out in the country in central California, amidst a bunch of orange groves. In the course of our walk, we had to cross a paved road that saw very little traffic. As we came back across the road on our way back, a pickup drove by just after we crossed. The truck stopped, backed up, and started down the maintenance road we were on. Bear in mind this was about 9 at night, so they weren't out to check on their irrigation hoses. I grabbed my mom and scooted into the trees, thinking the truck would go on. It stopped at the row we'd gone up, turned and started up the narrow row between the trees. This was starting to really freak me out, so I pulled my mom a couple of rows over and back under a tree. I unzipped my fanny pack, pulled my little Colt .22, my pathetic Mini-maglite, and waited. The truck stopped right across from us, and just sat for several minutes. We didn't move, and they couldn't see us, so eventually the backed out and left.
No idea why this happened, but let me tell you, having that little .22 in my hand in such a situation felt wonderful!
