OMG... your post sent chills up my spine.
Southern Cal has seen more mountain lion attacks lately, most notably a small boy who was taken just a few yards from his parents and the cyclist Anne Hjelle. The courage shown by her cycling partner, Debbi Nicholls, who stepped in to save her friend was well documented by the local media. As Hjelle as being dragged away by her head, Nicholls grabbed her friend's leg and got into a tug-o-war with the cat. Her screams attracted other cyclists in the area, who pumelled the cat with rocks until it let go. The two women survived, however a third cylist was not so lucky.

What's especially scary is that the attack occurred just 1/2 mile from a residential area. With urban sprawl forcing these animals into a smaller and smaller area, it might not be the last time we'll see this happening. BE CAREFUL!!!
