Completely disagree. Its that area right behind the shoulder blade and above the chest cavity, that is the no mans zone. It is all muscle through there except for the vertebrate in bewtween. If you hit a deer there, it is very difficult to get any penetration. Half an arrow probably. You may end up breaking a vertebrate and probably will shock the spinal cord which will make the deer go down as if he has been spined. Give him a couple of minutes and he will regain his use and be fine. I have seen two dead deer taken with a gun that when we skun them out there was an obvious arrow wound in this area. It is true. We can live with a broken vertebrate and so can a deer. Remember, the spinal cord is towards the top of those vertebrate. This most likely happens when shooting a a very steep downward angle and your arrow hits higher than desired
