Penn Cougar?

The Williamsport Sun-Gazette notes the finding of some large paw prints (as yet unidentified, so could be canine, no photo of the tracks is included online) a few miles from Montoursville, PA:

"The most recent tracks consist of mud on the paved road. Each print is roughly 3 inches long by 2 inches wide. From the back of the hind paw to the front of the lead paw, there’s a separation of about 21 inches. The tracks run east to west, from one cornfield to another."

A few other sightings are noted in the article.
