Dave,
Sounds like you have a nice place there to find some seng and have had good luck at that already.
My advice to any new digger is not to get too greedy with the digging. Only harvest the older mature plants, and leave the younger ones.
Even though 3 prongs are legal to dig, leave the smaller one for another year or two until they mature some. Give them a few years to make berries, that you can plant. Leave some of the mature ones too, so you can harvest berries off them each year and plant them to keep your seng population thriving.
If you take care of it, it will take care of you with years of fun digging.
If you abuse it, it will not last long at all.
You should also look into growing some wild simulated. Lots of info on here about that.
If you want to learn more about Growing Ginseng - you should buy the book (link below). Most of us here who grow it, have bought and read that book. He covers more than just seng too.

I have a list of all Registered Dealers for TN (2011 list). They will not put out a 2012 list for a few more weeks yet.
I checked it out and there is a dealer in Tazewell listed (see below).
Isaac Cadle - Skylock’s Pawn II, Inc. - 1520 North Broad Street - Tazewell TN 37879 - 423-626-2262
You should also check out our Friend Billy Taylor (who post here often). He is a dealter in KY and TN (possibly another state too) and I checked his profile and it list Middlesboro KY as his home. Below is a link to his website.

If you get to know Billy - I am sure you will want to sell to him - even if it is a little out of your way.
Good Luck !
