This is not the actual cow, I didn't have a camera available. As I was traveling west on Lower Aliso Trail in Chino Hills, making a turn, I encounter what I thought at first glance was a large mountain lion, almost lost my lunch. It was hidden well in the trees, as I got closer, clearly it was a large wild cow. The cow just stool it ground, it appear to be stuff, not moving or reacting to my approaching bike. I look for the horns, possibly it might make a charge for my bike. Who let the Cow out!
