Scent is the primary defense of most North American game animals. We have seen everything from scent wafers to carbon sprays to hunters bathing in elk urine. The simple truth of the matter is that once a hunter begins to walk and sweat his smell cannot be masked. The gentlemen who bath in urine merely smell to the elk as a human who was urinated on. We have found the best way to control scent is to keep our nose to the wind.
