Bear behavior is highly variable, an adaptive trait they share with humanity. Black bears are actually responsible for more attacks than grizzly. Running will only trigger the attack reflex.The standard advise is to stand your ground and become very vocal. If an actual attack happens, feignting death will not stop a black bear. A canadian friend ( and rated boxer) encountered a black in B.C. The bear reared and slashed his chest. He responded with a combination of punches to the nose,head and chest that sent it retreating. You really should do some further research and consider the use of a bear spray ( capsicum powder) if legal. Our forum member Rhawn has had several encounters and collects bear books.
