Had a buck come by me at 6:40PM Saturday evening. It was overcast, wet and gloomy so I didn't have great visibility but I could see him clear enough. He came from uphill from me and walked down at an angle to my right. He crossed an opening and I could see he was big enough (East coast standards) for me to shoot. He went behind a tree and I came to full draw. As he stepped into the next opening he was quartering away from me with his body in an uphill angle. I released the arrow and it looked good in flight but, due to the gloom I couldn't follow it's full path. I heard a satisfying hollow chunk as the arrow hit and he ran about 60 yards and looked back at me. He stood there for 5 minutes and then it was too dark for me to see that far. I waited 30 minutes before getting down. We found no arrow, no blood. The ground was wet making it hard to tell blood from water. We went to where I last saw him and nothing. We decided to wait until morning. It poured all night so all blood sign was gone. Four of us looked all over the mountain and didn't find the arrow or the deer. My only hope at this point is vultures lead me to the body and I can recover the rack at least. Bummer.
