New to this site, it's good to see some excellent posts here. The only so called "no mans land" is suppose to be an area just under the spine and just above the lungs. Having shot several deer in this region peronaly has resulted in a quik kill,with aheavy blood trail. I think you would be hard pressed to drive an arrow through that region and not severe at leat one lung. Perhaps a single blade broad head could pass through on the horizontal, perhaps. I think you shot above the spine also. Best of luck.... DFA
