Thanks for all these informative posts. Re: ItsPat (great name, btw!) post: of course I'm not advocating not fearing/watching for rattlers! Only putting it in statistical perspective--on our local trails (can't speak for P.V.) there have been, as far as I know, no injuries due to snakes--but many due to seemingly more innocuous things such as tripping, dehydration, and heat exhaustion. These are the real dangers. As far as the comment re: bears, I was only responding to a previous poster who'd said he was as scared by snakes as he was by bears. Comparing the two, I'd say the latter is far more aggressive/dangerous--of course, not that you are more likely to run into a bear!

Especially on this mountain, an extremely unlikely event. But ... if I saw that proverbial fork in the trail, and there was a bear down one side, and a rattler down the other, I would most certainly detour down the rattler side.
I think the point I'm making is that excessive fear of snakes leads people to do unintentionally harmful things, such as moving snakes, or trying to kill them. The majority of people are struck because they actually initiate an interaction with the snake.
