I agree on tracking and finding the deer if you believe your shot is good. Somehow the "backing out and waiting till morning" thing seems to have become the thing to do on tv...why, not sure when they can see the hit. In my experience, if you put the arrow through the boiler room they rarely go much beyond 60-80 yards and are often dead within 60 yards. My rule of thumb is to track it, and if I get to that 80 yard distance and the sign isn't strong then I might decide to back out. If the sign is strong, I'll keep following. I don't know about you guys but I feel like by looking at the blood trail and asking yourself how long something can survive with that kind of blood loss gives me plenty of clues. Scattered drops...not so good, a steady stream w big splashes, frothy...that animal is close and probably dead already. They only have so much blood in them and if the blood trail is consistent, it's dead. Go get it home.
