I took a shot last night from 20 yards with bow. It was at 5:45 so just a few minutes until legal shooting time was up. It was pretty dark. I felt real good about the shot. Deer was broadside. I heard the thud like I definitely connected. Deer ran hard after the shot! There were several doe with her. It sounded like she ran 30-40 yds and then turned around and ran the way she came, it sounded like trees falling! However the sounds may have been the other deer to. I went to the truck got a flashlight and looked for blood or my arrow. Could not find either. So this morning i searched all over. Nothing, but the sound I heard when the arrow hit is unmistakable. I did find a patch of hair about 20 yards away. I can't find the arrow anywhere. I have not found one drop of blood. Any thoughts on what may have happened.
