Wow, I want to see that! I looked at u tube and Google and tried a couple of routes to the video but evidently the network put a clamp on it. I can't find it, just a couple short stories about it. I beleive they're there personally. Just too many sightings not to be something to it.
This is a link to an editorial letter in my home town in Southern VA, which followed several stories that were ran in the paper about the local cats and evidence to support those claims. It has drawn quite a bit of attention as you can imagine.
I'm just waiting to run up on one some day, but, we've had high numbers of bobcats all of my life and I've only seen 2 alive, so if the cougars are that secretive we may never see one.
