I ALWAYS use the soaps, shampoo's, sprays, scentless bags, dress away from the truck, hang clothes outside when possible, etc and after killing over 120 deer to this point, some of those some big un's too, I feel I am doing something right.... I still play the wind, every little bit you can do to control scent dispersion helps...deer dont read books, so you never know where they may come from, and I feel by doing what I do, will reduce my scent stream......notice I said reduce, not eliminate...
