Even though it happened over 20 years ago I remember it like it was yesterday.I got on the tee of a 200 yard par 3 with water that required about 175 yards of carry.There were 2 guys on the other side of the pond on the bank looking for a ball at the edge.I was waiting when patiently when they waved to me to go ahead and hit. I had only been playing for about a year and like a idiot I obliged and teed it up and they went about looking for the ball. I skulled a 3 iron and it headed straight them.I yelled "Fore!". One of the guys stood up and looked and it smacked him right up along the side of his head and he went down like a sack of potatoes.I freaked out and jumped in the cart and drove over to where they were and the other guy was picking him up off the ground.The dude had a lump on the side of his head about the same size as a ball.I proceeded to tell him how sorry I was but the guy I hit said, Wasn't your fault,I was the one who told you to hit. I should have been watching! I honestly thought I killed the guy.
