Stupid is as stupid does.(To quote one of her must be relatives, or maybe that's an insult to forest)
I'd love to see the video of her provoking a "bluff" charge on a big old sow with a cub or two ----
I have twice chased a black bear, with cubs, up a tree. Black bears don't defend their cubs, like grizzlies do. I was on an unused bush trail with a 4x4 and two young nephews with me. Around a bend, thirty feet away, was a mother bear and two spring cubs. I stopped the truck, jumped and chased them. The old one ran away and the cubs went up a tree. i did it so the kids could get a good look at them.
Another time I jumped out of the truck and chased a mother and two cubs up a tree, so I could get pictures.
The people on these threads who have had no experience, whatsoever, with bears, are scared shootless of them. The old timers who spent most of their time in the bush, thought bears were about as dangerous as a pet cow.
One fellow I knew shot a spring cub every fall, for the fat. He said in over twenty years of getting a cub every fall, he never once had to shoot the old bear. He said, "Oh, they snort and nash their teeth and make the odd false run at you," but none ever attacked.
Qualifier: Black bears that have become used to people and getting feed from people, can be very dangerous and should not be trusted.
