If you hunt long enough, you will miss. I quit counting. If you hunt long enough, you will lose an animal. In the moment of truth, your heart is screaming at you, visions of your bow resting on the deer are filling your head, and so on... You know what I'm talking about. The shot may look great. The deer is close and calm, than nature takes over. We hunt these little monsters because they are smarter, faster and prettier than us. And with traditional equipment, they trully have the upperhand on us. (and we wouldn't have it any other way.) It happens to all of us.
That being said, brush yourself off. Pick up your baby and shoot her again. Take her out to the woods and bowhunt. Thats the only way to get past it. Best of luck, Bhill
