Other hunters might have tried to make the shot. He was within thirty feet, and there was time to raise my gun and aim for his head from behind. I started hunting to prove I could provide everything I'd ever need to survive. I can hunt, garden, and build a poor excuse for a cabin. I could live out my days in the woods until somebody discovered me, and that changes the rules of the game.
Life has rules.
Probably a good thing most of the time and especially on that day. I couldn't shoot a tom running like that. Those are the rules. Hunt ethically, take clean shots, and hunt safe.
