See, it's not so much grizzly bears I'm afraid of, but rather moose. Despite it being unlikely that I'll encounter one where I live, they're probably the most terrifying animal in North America. They stand around 7 to 8 ft tall at the shoulder, I've personally seen one use its antlers to shred the side of a tanker truck, and they do have the strength and capacity to derail train cars, which when unloaded, way as much as 5 to 12 school buses. Knock them off the tracks.
