As for where I hunt in Tn, it has gotten a lot better, most notably in the past 2 or 3 years. I had wrongfully thought the 2 buck limit has been in effect for awhile. (A limit has no effect on me because I'm only going to take 1 buck regardless, also, I spend 70% of my time hunting Kentucky, where I reside, so I don't follow Tn hunting as closely as I should). With all that said, I have been very impressed with the development of bucks I've seen the last few years in Tn. I think hunting pressure on my area has reduced greatly. One of the farms that joins me is no longer under deer lease so that's minus two Hunter's shooting basket 6's all season. Another neighbor has become more serious in time and runs a camera hoping to bag a mature buck. These factors alone have made a big difference. I now spend more and more time each year hunting Tn, whereas, 5 - 7 years ago it was a complete afterthought due to lack of mature bucks.
The biggest thing I've learned by observing the above first hand is this: the bucks on my Tn ground can get just as big as they do over on my Ky ground. I've come to truly appreciate the importance of and how big a factor age and maturity is. Because hunting pressure has decreased in my area, I'm seeing the benefits of an aged herd on the Tn property.
