Most-feared large mammals
1. Grizzly bear
2. Moose
3. Bison
4. Cougar
5. Black bear
(The moose was elevated during my recent trip to Wyoming. I hadn't realized they were so ornery. I have yet to run into a black bear on foot, but I'm molified by the stories I hear of how unornery they are. Bison are up there I think because of the horns, like moose.)
