IVe been hunting Delaware Co for close to 35 years now. Up until about 10 or 15 years ago, You'd be lucky to see a buck. I counted 85 deer one day while driving from Andes to Margretteville, and only 1 that I saw was a buck. If you got a 2 1/2 year old buck, he was old!! The last few years I've been seeing more and more bucks. And of them, more and more racked bucks. Not sure why, maybe guys have been letting them pass during gun season, and Spotlighting may be down. I think that this has come at a perfect time. Its going to take a few years before you really notice the difference.
Zones in Ulster Co have been doing it for a few years now, and you can really see the difference. Just my observations.
