It looked good at the hit, but after observing the buck for a few minutes I began to wonder. He seemed to vaporize in the still green hardwoods. I took up the trail in stalking mode, watching every foot fall and not breaking a stick or crunching a leaf. But when I jumped him from his bed, I had the diagnosis. Liver hit.
I gave the deer three more hours and three hours after that I found it. After all my helping friends had given up. Persistence pays.
