Great deer!
While we have obviously produced the world record non-typical whitetail (ever shot), I do not believe Tennessee can ever be a "Big Buck State" so to speak. While we may have 10 150" or bigger deer for every thousand bucks, Kansas, Illinois etc. have 100 such deer in a thousand. It is as much environmental as it is genetics. Our soil is terrible, we have little agriculture to speak of and our warmer climates do not foster large body growth.
We are right in line with the Carolinas, Arkansas, Georgia etc. If you are hoping to kill a 140" deer sometime in your life here in Tennessee there is a decent chance you will be rewarded. If you are hoping for a 175" Booner, it will be a long winter indeed. From what I can see, the herd on my farm produces lots of 120" 8-10 pointers but anything bigger is exceptionally rare. They will probably never exceed that regardless of how long they live. My buddy and I watched a grizzled, morbidly obese 7 year old 6 point waddle across a field last year. He may have been 110" at best. Pretty typical older deer in my parts.
