Hanna and his wife were hiking along a park trail over the weekend when they rounded a bend and came face to face with a family of grizzly bears, Hanna said on Tuesday.

The bears, a mother bear and her two cubs, were lumbering toward them, Hanna said.

Hanna said he and his wife and three other hikers nearby backpedaled up the trail to get out of the bears' way, but one of the 125-pound cubs started charging at them.

That is when Hanna said there was only one thing he could do.

"The animal starts coming for us, and I can't judge, because it happened so fast, 20 to 30 feet. I unloaded a blast of pepper spray, that was too far, I should have known better, but when a bear is coming to you, you only have four puffs, so I puffed the one and he still is coming and the wind took it," Hanna said. 

"I unloaded it about 20 feet, maybe 15 feet, real close to that, and the bear shakes its head. Then, 10 feet, it happened in seconds, and looking (at the bear) right in the face, and then bam! I unloaded the whole can in his face and the bear starts going back toward its mom and other baby.  And at that point I said, 'Oh, Thank God.'"

Five years ago, a father and his daughter were severely mauled by a mother bear and her two cubs on the same hiking trail.

Hanna said he is still shaken up and said this is the first time in all of his travels that he has had to use pepper spray to fend off a wild animal.
