RE: judging yardage help
My hunting budies and I have a game we play at the range. We all get one arrow and take turns making up shots on 3-D targets. The first hunter will step up without say what distance he believes it is and take the shot. The next hunter will take the same shot and so on. After everyone has shot everyone says what distance they believe the shot was. It is then checked with a range finder. Out of all three of us we now guess withing about three yards of each other and withing five of the range finder. The trick is to try and come up with deceptive shots.
