When I lived in Oregon I used to ride my dirt bike on old logging roads and often would come across remote camps and I am not talking recreational camps, I am talking blue tarp, garbage strewn camps.
I suspect they were meth cooking camps, don't know for sure because I got the hell out of there.
So I started carrying a side arm while riding, would be foolish not to.
I also know in Humbolt and Mendacino county in Calif. they advised people to stay out of the hills during harvest season.
