Roxborough State Park, Near Denver, April 30, 1998.
Andy Peterson was attacked by a Mountain Lion while hiking back down from Carpenter's Peak.
He backed away slowly, Pack and Coat in front of him, yelling as loud as he could.
The mountain lion pounced and got his paws on each of side of Andy's neck.
Andy used his pocket knife stabbing at the lion, as I recall it was a Swiss Army Knife, and his thumb to gouge the mountain lion's eye.
The mountain lion ran off and Andy survived.
Andy has since started the Mountain Lion Ministry and told his story for a number of years.
I have hiked at Roxborough a number of times, and I do carry a pistol along with a Swiss Army Knife when I do.
Maybe the Sergeant's Model being built in another thread would be the better knife choice.
But, I really do not want the lion to get that close.
