I was playing in the Castle Oaks Senior Mens Club. I started on #17 at Castle Oaks. On my final hole, #16, I was 100 yards from the pin. I was playing Titleist Velocity Matte Green. Just a week prior I researched golf balls and found that Velocity was a good match for my swing speed. I was worried about my 9 iron carrying the bunker. I landed on the fringe and holed out after 3 bounces. This is my first hole-in-one ever. Our club has hole-in-one insurance, so we all had a drink paid by the club.
