I live in SoCal but I hunt in the desert. If I see a rattler out in the desert is a really, really out of the way place (and one where I am not going to be camping at) then I'll let it live.
But if I see a snake (I'm not picky. If it don't have legs, it's a snake.) and it's in an area that gets frequented by hunters on a regular basis, it's dead. I have no remorse. It's just plain dead.
The only thing I hate more than snakes are chukar. Snakes I want dead. Chukar, well, I want them gut shot so it takes them weeks to die...
