sorry to hear you are having problems finding your deer. Make sure that he didn't back track on his trail and cut off in another direction again. Had this happen to my buddy last year. Track stopped and there was no blood. I walked back up the trail 35 yds. and found where he had turned around walked back up the blood trail and took off in a different direction. Do you remember seeing the arrow hit the deer. High, low, to far back, to far forward?
