Bear attacks are rare. But, they don’t always seem so because when an incident like what happened yesterday a few miles outside of Yellowstone’s east gate finds the airwaves, it tends to become pretty big news for a couple of days. And, more often than not, there are extenuating circumstances. In this particular case, there is a very good chance the bear’s recent interaction with researchers had something to do with an erratic mindset. And maybe that’s a stretch, but truthfully, most experts don’t know exactly why some bears run when they see people, others false charge or others make contact. Remember, Tim Treadwell lived with them for years before he was surprised in his tent by a bear he had interacted with countless times.
