Bears kill humans to eat.
It is just the old media being politically correct, when they say...it is just the mother defending her cubs.
Do you remember the "Bloomdale's little brass bells" joke ?
No idea about the bells, except that tourists put them on their shoes so the bears can find them easier. I coached 2 girls from Alaska and they both said that if I went there and wanted to get really close to nature, whistle while I walked through the woods. I walked up on a black bear on our farm once and it did scare the crap out of me.
I also think getting eaten by a grizzly is right there with shark on top of the "suck scale" of ways to die.
