That was a good suggestion. I agree that if the shot was what you described there is still a good chance you will find him. It sounds very possible that the arrow hit the opposite shoulder on the way out. Without an exit wound finding a lot of blood will be tough. Sometimes you might have to look for the tiniest specs on brush, grass and just falling to the ground to keep on the track. Don't worry about frothy lung blood, especially without an exit wound. Get back out there and get some buddies if you can. Get someone experienced with blood trailing if you know someone. Most importantly, keep a positive attitude. If what you said is true, you will find him.
