I will shoot the first legal deer I see. I am out of venison and I am hungry. That being said, last year on opening day southern zone rifle I had a shot at a doe right at first light. Right before I took the shot I heard some rustling of leaves on her back trail. A couple seconds later a buck stepped out. A couple minutes later he fell down. A couple hours later I was not hungry anymore. I would have shot the doe no questions asked though if I did not hear the rustling. Shooting the doe would probably have scared the buck into not following her trail anymore and I would not have gotten him. It is a chance you take.
