Even black bear sows with cubs are bad juju. We drove around a corner on a logging road up in BC this fall and there was a yearling blackie standing on the shoulder so we pulled over. When it bailed off the road we got out to maybe get a picture before it disapeared into the alders. I immediately saw momma and the second yearling at the bottom of the embankment and they scrambled about 10 up an aspen in the middle of a thicket of 6-foot alder to get a better look at us. The aspen was probably 25 yards from the truck, and when momma came back down in a hurry I got the hell back in the truck pronto. It would have been nothing for her to come out of that patch of alsders at us in a flash. They can do allot of damage to a person fast.
