A veteran hunter will know from years of watching animals and studying their body language, just how much time he has. Usually it’s more than you would think, and it increases with the distance between you and the victim-to-be. Whitetails, for example, have a distinct facial expression when things are not to their liking. It looks like a frown. Years ago, sitting in a rhododendron patch on a West Virginia hillside, I was approached by a doe and a fawn. The doe was perhaps 10 feet away, and there were enough of my scent molecules in the air to cause her concern. The expression on her face was that of a Detroit automobile industry executive pondering his/her future. Then she got the full load of essence de Petzal and ran like hell.
