I would look for property along the Dripping Springs Escarpment, which physiographically separates the ridge-and-hollow hardwoods north of the escarpment with the more flatter agricultural regions to its south. These agricultural areas provide nearly unlimited nutrition to deer using the more rugged uplands along the escarpment as security cover, creating a well-fed and older age structure of buck. This is one of the areas of KY that is producing so many record-book bucks.
The Dripping Springs Escarpment in KY runs along an arcing path from Marion, to Princeton, to Hopkinsville, then Elkton, and then Russellville, Bowling Green And Cave City.
Here's one guy's website for finding leased land in the area, as well as in northwestern TN. Jimmy is a pretty solid guy:
