When a buck walks through the woods, the one body part that leads his way is his nose. He trusts it and relies on it for his survival. His nose is truly remarkable. It is estimated that a whitetail has more than 60 times the olfactory range of a human. In the right wind conditions, a deer can smell a hunter a mile away.
