I coached HS golf in Felton, CA a few years back and during a practice round, hole 5 , 139 yd uphill par 3, I had an ace with a 9 iron. For added drama, I had my entire team plus 3 coaches all watching and witnessing. 6th hole is above 5 green so the group ahead saw clearly. The group that just finished watched from green side and I had 2 groups w my on the tee box. Although I didn’t see it go in , my assistant coaches signaled as it spun back into the hole on a sloped green back to front. 14 witnesses , thank goodness most of them were underage .
