Don't always count on the wind. Trust me, it can change direction in a heartbeat. Be as scent free as you possibly can. Scent free detergent and scent free soap-shampoo will help. Go to Walmart and get Arm & Hammer scent free deodorant. It costs a lot less than hunting brand deodorants and is just as good. Brush your teeth with baking soda instead of tooth paste on the morning of your hunt. Is all of this necessary, no, but it will help even the odds.
