Its entirely possible. I won't rule out the possibility. People can laugh all they want. I also would like cold hard truth of this as well, but if we do have them in the northeast, it wouldn't suprise me.

Actually my father claimed to have seen one sunning himself on a laydown a few years back on Beach Creek mountain here in PA. He is definitely not one to lie about anything so his story may hold truth. He just said he can't exactly say for sure it was a mountain lion, but he doesn't know what else in PA that looks like that. He said it leaped off the tree and disapeared into the laurel shortly after he stopped to have a better look.

I can tell ya one thing. If in fact we do have them in the Northeast and we end up with enough of them that they aren't too rare to see, I'll be packin heat come archery season along with the bow. They are nasty critters and have been known to stalk people without you ever knowing they were there. I'm not a cat fan and don't care to have any of them in my home state.
