Just on the news today. Mountainbiker on Serrano Cow Trail in Whiting came face to face with a mountain lion. It seems that the lion jumped out of a tree onto the trail about 10ft away from the moountainbiker and started walking toward him. The biker used his bike as a shield, threw rocks and yelled. The lion finally stopped approaching but did not back off. The biker started walking backwards until he felt safe enough to turn around and start riding away. He came across hikers who also saw the mountain lion. THis is the second time this happened in this area within weeks. Pretty scary.
