NOW, with that said, let's step back for a moment, and think about the basic premise here. You are stranded deep in the wilderness, like the guys in the "I shouldn't be alive" TV shows. I'd say your statistical chances of having a Wolf or Bear or other potentially "harmful" wild animal encounter has just risen in logrythmic proportion to the base population of North America.
Having followed a few of those links, it doesn't look like you have to be stranded anywhere, or necessarily even "deep" in the wilderness, or even be injured, to have a bad wolf encounter. It also appears that if you believe all the stories floating around, then the chances of a wolf encounter are higher in some areas in North America than it has been in the last several decades. OTOH, this is somewhat by design since we've been reintroducing wolves into areas where they had previously been driven out of.
That said, there's also lots of stories floating around about people (frequently children) being attacked by mountain lions. Joggers in semi-wild areas near population centers sometimes have an unhappy mountain lion encounter as well.
And then sometimes people get attacked by bears.
And then sometimes people get attacked by packs of wild, but formerly domesticated, dogs.
And your pets, both dogs and cats, can be attacked and eaten by coyote, mountain lion, wolves, etc.
It's a bitch being out in the wilderness, that's for sure. My thinking is, if all the horror stories scare you, then stay out of the woods.
Look, the mass media is insanely good at scaring the crap out of us. Some kid shoots up a school thousands of miles away and suddenly we're all ready to ban all the bad guns. Some sex offender snatches a kid from a park hundreds of miles away, and suddenly we're wary of every male stranger we encounter, everywhere, all the time. Some guy tries to light his shoe on fire on a transatlantic flight and suddenly we all have to go barefoot everytime we get on a domestic flight. Oh, and now we can't bring water on the airplanes anymore.
The list goes on.
We can huddle in fear in beds (until a fat man in a small plane has a heart attack and crashes into our bedroom), or we can shrug it off and live our lives.
Personally, the only thing this thread has done is convince me to carry a gun when I go into the deep wilderness, especially if I'm doing it up north. That, and it makes me want to renew my tree-climbing skills. But a spear? Naw. It's interesting reading some of this stuff but I can hardly bring myself to bother with a walking stick, much less a spear.
We need a thread on the best way to carry a handgun when hiking/packpacking in the deep wilderness. Frankly, I don't think a gun in my backpack is going to do me any good if I really need it. But carrying it in a holster just encourages some park ranger to take it away. I guess it's good that I typically hike with a possibles bag.
Sorry for the off-topic rant....
