Shot my career low 9 hole score with a 31 (five under) on the back nine for a 38-31=69 at age 75 and 10 months old with my favorite ball a Titleist Pro V1x and a Titleist ZB forged 8-iron into the hole. I started the back nine with 2 straight birdies then a hole in one eagle next, finishing with another birdie for 5 under for the nine. Enjoyed it immensely!
