Still laughing at the mental image. Holy crap. Apparently since it was on the woman's home turf, there is some part of the ursine brain that recognizes territorial rage/dominance, and acknowledges its higher place in the pecking order.
How else does a bear not shred her like so much papier mâché? Was it a bear cub?
I assume it was a young bear, that scheme would be unlikely to work with a full grown bear.
That said, I've met some pretty tough women in rural areas, and some of them had no trouble putting big, tough guys in their place. This lady sounded like one of them.
