Self-inflicted hit of pepper spray drives off an attacking grizzly in Grand Teton National Park

While mauling a hiker on Signal Mountain, the grizzly bit into the man's can of bear repellent and was hit with a burst of it, causing the animal to flee. The 35-year-old Massachusetts man, who'd pretended to be dead while he was being bitten, made it to safety and spent Sunday night in the hospital.
