Hitting into stiff 15 mph wind gusts on a beautiful 50 degree sunny December Friday. Temporary tees in place for the winter, not in season, so not official according to the our club's men's golf association. Not a problem - It's still my first Hole in One after playing for 35 years! It was a great shot - I saw that it was tracking nicely - I said to myself that's a nice shot - Bent over to pick up my tee (I did not see the ball go in the hole!) - My Buddy watching said "it's in the hole!" - What a great feeling I had even though I did not see the ball drop (ProV1)!
