Road blocks are often cause for aggravation, but not when there are two cuddly bear cubs playing in the road. 

An unknown visitor to Glacier National Park in Montana recently captured this footage of two bear cubs whose playful antics turned into a road block on a popular thoroughfare. 

There was no sign of the mother anywhere nearby, but you can be assured she was keeping a watchful eye somewhere out of sight. Onlookers kept their distance as the cubs moved on before long and the show was over.
