Hunting in far S. Texas close to the border is a whole new ball game nowadays. And I'd bet it's probably worse in some parts of Arizona.
Personally, I've never had a problem here in TX, but I don't go ANYWHERE without a handgun nowadays. And if I'm in far S. TX, my Handgun will be a Hi-cap Glock. Usually my Glock 32 in 357 sig with a couple of extra 15 rd mags to boot. It also works really well on feral hogs and Javilinas.
