The wind is your friend but like its been said, its not perfect out in the woods, if so, everyone would fulfill their tag each year. Do I believe washing your clothes and using a cover spray gives you a confidence that you are less likely to be winded than just walking into the woods and not using anything. I use Wildlife Research Scent Killer in their Fresh Earth line. I wash my clothes in this and then store them in a big rubbermaid tote and put H.S. Fresh Earth scent waffers in it. I shower with H.S. Scent-A-Way shampoo/body wash (the green stuff) and I use the W.R. cover spray when I go out. I believe this helps "mask" any odor I may carry around but I know its not fool-proof. I know you cant always play the wind and I've gotten away with it and not been winded when the wind was not in my favor using my "scent-cover" system, so I will continue to use my system. Play the wind when you can, move slowly, and keep your eyes and ears open as those are more of key factors in getting deer close to you.
