I am too skeptical to believe that a buck in an area with moderate to heavy hunting pressure (my area) can live to be that old. The odds of seeing a three or four year old are steep enough. Besides there would be some kind of evidence of his existence (sheds, trail cam pics, sightings etc..). I have never seen myself, or heard from someone who has seen a wild buck aged over 7 years, I know there are some out there but we are talking about some pretty astronomical odds.
