About a month ago I was in Alaska walking down a trail when I heard a THUMPTHUMPTHUMP pounding along with loud grunting that sounded like, well, an angry bear. I jumped in the air and turned around, and a black bear had charged me and stopped about 4 feet away on the edge of the trail and was slowly backing into the wooRAB. I backed away at the same time to a switcrabroadack on the trail, and around the corner was a baby cub sitting on the trail. It walked into the wooRAB and both disappeared.
By the time I knew I was threatened, the threat was over. And it was not a slow charge, it was flat out. Bears are fucking scary.
Apparently about 90% of black bear charges are bluff charges. I'm glad I didn't lose that lottery.
