Where i hunt there is alot of horse riding trails, so i think the deer are used to humans. I can say that I have never been busted by a deer smelling me. I had to babys and a spike come 10 ft from me yesterday with out ever knowing i was there. I was in my stand about 12 ft up. I do use cover scent but i wash my clothes in regular detergent and I dont store them in special plastic bags.
