I stopped using cover scent 10 yrs ago and the size of bucks ive killed has gone up. I used to have snort and blow when they smelled that stuff. Now they never do. I also have come to believe that deer are like dogs that bite you when they sense that you are afraid of them. If you completely stop worrying about the winding you they dont seem to even pay attention to you.i have had a ton of deer really close to me that never even looked at me. Where i hunt deer come from any direction so i never fear the wind, just hunt prime time.
