RE: Mountain lions in PA!
I am in Connecticut. I have connections to state biologists and have been told that they will not confirm because they do not want to create a stir and have anyone hunting (poaching)them. I have several friends that claim they saw one and I believe them. However 2 months ago a friend of mine showed me a picture of a mountain lion plain as day on the edge of a corn field with a radio tracking collar on it. This was on the NY/CT border. I know where the picture was taken and it was not doctored. The dep from both states were out and saw where the pix were taken and they made plaster casts of the tracks. This was in the town of Northeast. Now, I challenge anyone to call DEC in NY and get a confirmation that this occurred. I will guarantee you that they will deny it even though they have pictures in their hot little hands.
As far as the conspiracy theory post above, In states where they are abundant few people see them also. They are a very secretive animal and guys chase them for miles with dogs before they get a glimpse, let alone a shot at one. I firmly believe that they do cover it up.
Up in another town in Northwest CT I have a friend who manages a large tract of woods, 6000 acres actually. He found tracks of amountain lion and a friend of his is a guide for mountain lion in Oregon. He saw the tracks, measured them and believes with out doubt that they are from a mountain lion.
