RedCloud you have it nailed! Just think how much skin your body sluffs off a day. We have so much dead skin that falls off and this is what the deer are smelling. Even with long sleeves on, your hands usually touch weeds, sticks, ect. This all goes back to a deers survival.... they spend 365/24/7 trying to just stay alive! I couldnt imagine living all day & everyday on edge like deer do, this is what makes them the way they are and why WE are addicted to chasing them!
