I too have been going to the deepest, darkest hollers to look as well. It seems that here if I can find a good sized pawpaw patch and look under it, it's been dark enough to support the plants longer. I have, also, but with much less success, turned the very top of the ridges. I don't find many plants but the one's I do are the mature, old growth stuff that most guys won't climb for or even recognize, but the stems are big as a pencil and the roots are deep. Big seng looks much different from what most people dig.They often walk or drive right past it without knowing. Sorry to hear it just ain't me with the dry problem and glad I found this forum.
