I think most people have experienced what you have (bad run) at some point or another. I know I have, sometimes things just don't go as planned or turnout like theresupposed to do. I've had deer hit perfect, right through the heart run further than I ever expected them to.

I once lost a deer (gun season) that ran across an open field of tall grass after I shot her, I lost contactwith her for a split second and she was gone. I searched for 6 hours that night and couldn't find her. I gave up till the morning only to trip over her (literally) walking back to my truck....RIGHT IN THE MIDDLE OF THE OPEN FIELD where she was running. I guess when I lost eyesight with her for that split second she must have augered in right there and I walked right past her. More than once because I kept going back to pick up the blood trail time and time again.[&:]
