I was on number 4 at Twin Pines in Cedar Rapids, Ia. 184 yard hole. Small green and a 15-20mph wind in my face. I hit my 5 wood and the ball went straight at the green which is unusual for me. I rarely hit this green. It is a very small green and it is like an upside down saucer. It hit and bounced and started to roll and I said it has a chance and then the ball disappeared. I thought because it was a back pin the ball rolled off the green. I walked up to the hole a peeked in the cup and there it was...my second hole in one
