At 28 yards he pauses looking for me (the buck that grunted) and I drew, placed the 30 yard pin low on his heart and......whispered, "I win" and slowly let the bow down and hung it up.
I love that feeling

Wether you let him pass or let the arrow go you've won!
That's an interesting story. I've never heard that sound but I've still got a few years to go to match you years in the woods. It would have been cool if he did it in front of you. It almost sounds like a sneeze but it's hard to tell. Thanks for sharing.
