Lukie, where do you live? In Colorado on the front range, if you are hiking you really do have to consider mountain lions. There are warning signs on the trails up in the foothills.

They say for mountain lions, make noise at a low pitch (show that you are male) and raise your arms up to look big. Don't fucking run, it triggers the chase impulse in them. They say to pick up small kids so they dont run for that reason.

If they DO come at you, throw shit at them, like rocks, your cell phone, etc. My uncle that lives at the trail head will pick up one big rock and a handful of little rocks if he hears something he doest like. Little rocks to throw in the eyes, and big rock to club it in the head if it comes to that.

oh and wufwugy, good point about the neck. I imagine it would be pretty tough to do that.
