Never been to Asheville myself but we get loads of big cat sightings here in Wales too, so I find this stuff really interesting. Black panthers (or whatever they actually are) seem to pop up all over the place in rural areas and nobody ever gets proper proof.
What did it look like exactly? Like genuinely big, bigger than a dog? That's usually the thing people mention first, just how massive they are compared to what you'd expect.
Would love to see any photos if you managed to get any. Even a blurry one is better than nothing honestly. And did anyone else in the area report it or was it just you?
