Great topic. Shot a doe this year-double lung (so I thought), couldn' t find her. Looked for nearly 12 cumulative hours. Blood dried up and she was gone. Next day was nearly 80 and lots of coyotes around. I even waited 1.5 hours after the shot. Don' t know how to explain that one. What I did want to say is look for crows the next day. I found a huge doe that way - i hit high and back as she stepped away just as the arrow left my bow. It got her in the back and went between her lungs piercing the diaphram. After the hit, I watched her run for 50 yards, then slow to a trot and circle back and disappear. She went about 400 yards. Couldn' t find her that night because of heavy rain. Went out the next morning, saw crows circling and being really loud - lots of em, went to see why they were congregating and walked right to the deer.
