RE: Could not Recover Doe...
The best hunter I ever knew convinced me that if you do not actually see the deer drop, wait at least an hour. That advice has resulted in more than a few deer, or at least made their recovery easier. It is the one thing that most bowhunters do better than gun hunters, waiting that hour (which always feels like 1 day!) before picking up the trail gives you a much better shot of finding them, or making a second finishing shot with a gun.
