One of my uncles shot a black bear many years ago in PENN, lung shot and the bear started running around in a circle as if trying to bite its own tail. He shot it again and it dropped dead. Another guy I know shot a black bear during a drive in PENN and the bear ran to the closest tree, climbed a good 10 feet up, gave the death bawl and crashed to the ground. Said it startled the heck out of him.
