IMO that pic shows what I mentioned and others talked about. I think that arrow is above the spine and in the back straps of that deer. The anatomy pics and the one butcher cutting pic show how low the spine is, and to me it looks like that deer is shot above the spine. I think I tried to explain it, but I do not think there is a dead zone in a deers lungs, but I think people do not understand how low the lungs and spine is on a deer. One thing I read in here and on other forums is "the deer ran for over a half mile and we lost the trail" or stories of tracking a deer for a long time with poor blood and lost it after six hundred yards. I think they are examples of pushing a deer to fast and to soon. The last buck I shot I sat in stand for about half hour after the shot, and I knew it had crashed, but you never know. I then got out of stand and slipped out as quite as I could and left. By the time I tracked deer it was around an hour and a half later. That pics shows that a pass through does not equal dead deer, but also shows how low the lungs are. A nice size back strap is about four to five inches around. Then you have the hide on top and the ribs below, the lungs are low!
