I'm not concerned at my property, but there is a property that we manage the ponds on that is owned by an absentee landowner. There have been some theft issues a few years ago, some trespass issues, and I've seen burned spots in the road very close to there that I assume was from a small meth lab being disposed of (at least that's what the local paper said). Since I have a lifetime Personal Protection license, I think it's better to be safe than sorry. I wouldn't be that concerned if I wasn't alone, but you never know.
I haven't ever heard of a coyote attacking a person around here. California? Sure, especially around L.A.
CJ, the Western 'yotes have paler fur, and it's denser and longer too, that's why they get more $$ for them.
