Come on Justin.
Let us not turn this into an our bears are wickeder that your bear, thing.
I've been around Grizzly and yes, they scare off...................sometimes.
In 84 or 5 my x and I were hitchhiking through Canada up to Alaska and back.
Saw plenty of the buggers there, camping out every night.
More of a nuisance than a scare, though.
But when we passed back through northern Idaho ( I think, been an ungodly lot of years) we saw an article in a local paper about a female ranger who had shot a large male Grizzly.
It had done 2 of the fake attacks that they will do, and she had just held her ground.
3rd time she waited till he was real close, and put a bullet from her .357 Magnum in his brain.
Dropped him on the spot.
Talk about being cool under fire!
The newspaper guy asked her why she'd shot the 3rd time and she told him, she just knew that one was for real.
