I use nothing but the wind. If it isn't right I'll hunt some place else or stay at home. Luckily I have plenty of places to hunt. It's funny to me one of the scent cover sellers has an advertisement that boast of covering "repicated human odor at Rutgers University". You would think that somebody at Rutgers would have natural human odor they could cover up............ When they prove they can beat the nose of a bloodhound in independent test I'll start believing in their products......
