After I hit the green, we saw it roll towards the pin. Due to the contour of the green, we could not see it roll in. Thought it was close, but when we approached the green, no ball in sight. My playing partner thought it might have rolled off the green. After a few minutes looking, I went back to the hole and there it was. What a sight. First hole in one with a witness. I have been playing Titleist balls for years, and plan to stay with them.
