it happens, the point has been made that once we have exhausted every effort to locate the animal then we have give up. Now many lost animals can be attributed to poor shot selection especially with archers. Seeing the exit path of the arrow goes a long way towards waiting for an ethical shot. I've never lost a deer with a firearm, however, that's not the case with archery equipment. I wish I could take back a couple of poor shots over the last 40 years especially youthful mistakes.
