Good topic and good info. This fall I helped the other guy who hunts out where I do track a buck he shot, it was a quartering away shot and he hit the buck through the liver and clipped the left lung with a pass through, he found the arrow and the was blood but not enough to identify a good clean shot, there were not guts on it, I had just got off work still in my uniform, grabbed my bow, and hutning pack took my BDU top off and helped him track it, I found the blood trail about 20 yards from where the shot was, not a lot just a couple of drops and so I went and started marking the trail with hot pink tape and that buck ran almost 150 yards with a clipped lung and a good size hole in the liver, found it after about 2 hours of looking for it.
