BuckeyeSW,
I also want to welcome you to the Wildgrown forums! We hope to read many of your adventures about Ginseng and herb hunting in the future! It would be great for you if the 3,000 acres of virgin land that you noted, is in fact virgin land and has not been hunted. However, it is getting harder and harder to find such locations as more and more folks are getting into Ginseng and herb harvesting and also, so many more Ginseng Poachers that care little of property boundaries, Posted signs and whether the Ginseng belongs to some property owner or not.
It appears that there are some great locations to search for Ginseng in Southwest Ohio West and East Southeast of Cincinnati along the Ohio River. The hills, ridges and bluffs along the River should be ideal locations for Ginseng habitat.
Good luck!
Frank
