That's a great youtube channel, ever watched it?
He interviewed a middle aged guy from Appalachia named Beaver. Poor AF. Dude did all kinds of odd jobs, hunting ginseng, carpentry and growing weed to list a few.
It lead me to believe that the real deal skunk is gone. Just a hunch. But if it was around, guys like Beaver would be growing it, and getting it out to the public. He was direct lineage of that area and I believe would have access to a skunk cut.
