Tourists scatter and flee in Yellowstone National Park as mother bear chases them away from her brood

Cute, small and fluffy, these little black bears seemed to melt the hearts of visitors at Yellowstone National Park this week.

But their cooing soon turned into screams when the mother sow decided she’d had enough.

She started to chase, followed by her brood, and the tourists were forced to run.

‘Keep going! Go! Go!’ park ranger John Kerr shouts at the families as they leg it across a bridge in the Montana sanctuary…

A great excuse to look up and display this hilarious Gary Larson (Far Side) cartoon. He really was a funny cartoonist, unlike Garry Trudeau.
