I've never watched a bear drag anything away, but have run across lots of their buried treasures (I really don't like that.........). But one of the most impressive things I've seen (more than once) is a grizzly running for its life as I entered the valley or area (they heard or smelled me/us coming).........especially in the fall when they're fat and their fur is thickening for winter, and their hide moves like Patty's in the PGF. Bears can really cover territory!
