2, one was during my 2nd year bowhunting, was a smaller buck but I clean whiffed and shanked the shot in fron of him. The 2nd was far more painful, it was on a definate book buck. I misjudged the yardage. The buck came in a spot on a small trail no deer had never approached from in all my years of hunting that stand. I shot and watched the arrow fly true...until at the last second she ran out of gas and dropped right under the buck and stuck in the ground behind his front leg.[:@]I could've puked.
