With hunting season here, more and more people are taking to the hills to bag a beast. With humans encroaching on mountain lion habitat, more and more lion sightings are reported. But, they are a ghostly creature. Some humans don't even know they are being watched by a lion when in the woods. The feeling of being watched or stalked is scary enough as it is. But, the sound of a mountain lion screaming is absolutely terrifying.

As an avid outdoorsman, I have only heard a lion scream once in my life. The sound made the hair on the back of my neck stick straight up. For anyone who has never heard the sound, check out the following video, and be not only "bear aware" but "lion aware" when in the great outdoors.
