Grizzly bears can run at up to 35mph, so if you're too close then there's precious little time to get out of the way. That's a lesson two tourists learned after accidentally antagonizing a mother and her cub at Grand Teton National Park. In a video recorded by another visitor, the pair can be seen standing outside their car to take pictures of the two animals at the roadside. Unfortunately for them, the sow takes exception to this and charges, forcing one man to race inside their car while the other climbed onto the roof.
Of course, had the animal really wanted to, it could still have reached him with ease. Though black bears are more proficient at scaling obstacles, the National Park Service (NPS) explains that grizzlies are capable climbers too.
