Why, yes, they are. Look, for example at this one! He's just coming up for a little ear rub. No need to panic.
We could ban hunting in those parks, yes, but somebody is going to have to tell the bears.
Grizzlies are naturally curious, very intelligent, and just like a child and the grizzly in the video, keep testing the limits looking for the weak points. This particular bear is frightened by the stick and by the shouts to get away. I don’t know whether the guy taunting the bear lived or died - it could have gone either way.
