You know, I agree with you there. If people walk/jog/hunt/sight-see "fat dumb and stooo-pid" in areas where dangerous animals are KNOWN to be hanging out, without having any means of protecting themselves, perhaps they will get killed. That is a predators instinct, to kill. Animals have NO way of reasoning.
And man has a natural instinct for revenge. And they can reason. Which should have told them to stay out of the darn woods where there are killer bears in IN THE FIRST PLACE!!
But I wouldn't dream of suing anyone if an animal attacked me or the landscape or the weather got the best of me. That's part of the bargain and it's all my choice whether I go in unprepared, lightly outfitted or loaded for bear. Stupid or seasoned everyone should have to accept that as the reality of wild lands IMO. But I'm old and cranky about it.
