Dumpy,
I don't know if Max Patch is a part of the Harmon Den Wildlife Mngt. Area or not. If it is, I don't think you would be able to dig. If it is just a part of the Pisgah National Forest, you probably could. The state line is real close there and that is part of the Cherokee National Forest. That is where I had just come through from and then passed into N.C. I hope this helps.
I was scouting some territory this morning at the 3000 ft. level and I found a couple of 3 Prongs. They were still green and had red berries on them.
