I have photos of a red truck with Alaska plates chasing a sow and cubs down the road at Chilkoot. They show a bear on its hind legs, nearly vertical, trying to get out of the way, but only yards from the truck. In another incident, a truck came around the corner without slowing down and cubs had to leap out of the way. A truck and boat stopped by the crowd, and out came a laughing female fish counter and, I assume, her supervisor. The state of Alaska has a legal responsibility when an incident will occur. Best wishes to the bears and the bear foundation folks.
