Bears rub on many objects other than trees. This clip shows a grizzly bear with two yearlings rubbing on a wooden bridge on a decommissioned forest road. Barbed wire is attached to the wooden bridge beams and the bear rub tree next to the bridge to collect bear hair. This footage is still photos from a remote camera that have been stitched together in sequence.
