I don't think anyone has stated that it would be impossible to have a mountain lion in either state.Unfortunately,despite the thousands of sightings,no positive proof has ever been confirmed.The vast majority of people simply have no idea what they're seeing.Dig up some old threads with poitive proof and you'll see what I'm talking about.People think housecats and bobcats are mountain lions.Mountain lions leave sign.In PA,THEY MUST NOT EAT OR WALK ON THE SURFACE.
