A buck I had been hunting finally came in (a few years ago) and I drew as his head went behind a tree. He stopped when his head and part of his neck appeared on the other side--COMPLETELY BLOCKING THE VITALS [:@] He eventually spotted me and after a hold of 1 1/2 to 2 minutes he started to bolt. He stopped about 30 yards out with only an inch or two of the vitals exposed--nearest the paunch. I took the shot and just barely touched the tree that was blocking the rest of the vitals. Luckily it defelected the arrow enough to miss him completely instead of a paunch shot.
