Here's a definition for you: "ANY DEER HARVESTED UNDER FAIR CHASE CONDITIONS IS A TROPHY IN THE EYE OF THE BEHOLDER." When my son begins hunting THIS is what he will be taught to gauge his success by. Obey the rules, excercise personal ethics, and at the end of the day, it doesn't matter at all how big or how old your deer was...or even if you killed one. Anything less than this is superficial. I would never think of imposing any limitation upon him other than those imposed by the law. If he wants to gladly shoot every legal yearling buck that waltzes down the trail, it's his choice. If he decides at some point to limit himself, good for him, but it really doesn't matter to me in the least, as long as he enjoys what he's doing, obeys the laws, excercises ethics in the field, and continues to spend time outdoors with his Dad.
