Hit a strong PW to a very uphill 95 yarder. From the tee you can't see any of the green. Luckily, there was a mower operator near the green that witnessed the shot. Since the cups have inserts that will not allow the ball to go it, he said it ran past the hole and rolled back to the front and gently hit the stick, stopping 4 inches away. He stopped us as we headed to the green to tell us that that was a hole in one or we would never have known the ball path and it would have just been a pick-up birdie. Thanks to the course crews working through this pandemic.
