He had a gun with shells in the clip within 50 yards of a R/R. He was on a public WMA, not land that he owned or a family member owned. He was on a WMA, on a scheduled deer hunt. You can't have a gun a WMA unless it is a special "GUN HUNT", so that alone should state he was hunting, hunting, hunting.....What else is there to understand????
Understand this: the game warden even ruled out that Bucky was "using" his gun. He told him the gun didn't matter, and that he would be guilty even if hes was carrying a bow.
Is there any doubt that Bucky was not "using" his gun which was the only hunting device he had at the time?
So, if that's the only piece of the definition you can come up with, even the game warden disagrees.
