So I just watched this video on Fox News. He was doing a run on a mountain path when he encountered some mountain lion cubs, although he didn't know what they really were when he first saw them. Next thing he knows, mother mountain lion starts to follow/stalk and lunge at him several times. He had to walk backwards for about 6 minutes (6 minutes of terror) before he threw a rock at mom and she finally ran off. Scary video!!
