Hole in one on the mule face green

Green is up hill so you can’t see it just the pin flag. 155 yards out grabbed a 7 iron.. hit the ball well aiming about 10 yards to the right of the pin. While the ball was in flight both guys I was playing with said “ you r going to like that ball”. They kept saying that until the ball dissappeared. One made a comment that that ball is going to be in the hole. We drove the carts up to the green. As we got to the top and could view the green there was no ball on the green. Oi told the guys I don’t see any ball on the green. I looked in the sand trap. No ball. Walked to the hole and there it was!
