Ran into a bear cub this evening on the mountain. Thing was rolling around in the snow for a long time like my black lab. Just upside down legs up and rolling in pleasure.
Then he saw me, was a little spaz. Ran to a tree and climbed to the top, then climbed down as fast as he went up, ran back out onto the snow, rolled, then took off towards the other side of the trail.
Never saw another cub or a mother, he seemed solo. Maybe a very young guy on his own for the first time? He was smaller than my black lab but acted exactly like a puppy. Just wanted to play it seemed.
