hung lo i dug one about ten years ago and i have never seen one since. It was the biggest top i have ever seen. I wish i would have had a camera back then. The plant was growing on a rock covered in moss i didn't even have to dig it. I just picked it up and shook the dirt off. The plant was almost four feet tall and the top was huge on it. The root weighed green 8 ounces still to this day it is the biggest root i have ever dug. Probably will never find another like it. But i guess thats what keeps us going.
