I am 150% certain that I saw a mountaine lion in PA about 5 years ago. I was spotting in next to the Alvin R. Bush dam and we saw eyes on a horizontal tree feet off the ground. After about two seconds it jumped down and calmly walked parrallel to the road. We got a great look at it...way to big to be a bobcat, and the 5 foot long swooping tail gave it away immediately. It was by far the most majestic animan I've ever seen in my life, when he walked it looked exactly like an african lion the way their shoulder blades move. THEY'RE IN PA.....TRUST ME
