I usually don't trek very far,
when all around me black bears are.
Hi...
I no longer carry a firearm when camping. I do carry a pocket knife and a multi-tool. In addition, I carry a sheath knife and a machette, both for general camping use, when necessary.
Although some of those could be considered personal protection weapons, I don't think any of them would be any good to fend off large bears, for example.
Of course, I could always pretend I was Ben Lilly (Google him, and you'll see what I mean)...!!
