I've known to snap hook it when I try to give one too much juice. And I mean snap. Hit the maintenance cart this summer on a drive that started out on the far right side of the fairway, and it turned straight left. Followed the flight path and here came the guy on his cart on the far left, and sure enough, it hit him right in the side of the cart. After I apologized, he laughed about it and said he was watching the shot, and had never seen a ball start out that far right and end up that far left so he thought he was safe.I've lost track of how many times I've hit myself while teeing off. If I'm in the tee box, you take cover.
