An extremely windy but hot day (86 degrees). #12@River Glen, White tees set at 150 yards, front pin position 17' from the front edge of the green behind the newly renovated sand bunker. I hit my 7-iron, my Titleist Pro V1 was tracking the pin, took one hop, then dropped into the hole. I did not think it went in as we could not see the bottom of the pin from the tee. When we approached the green there were no golf balls on the putting surface (my 3 fellow golfers had all missed the green) so I knew it was an Ace. Carry over hole...I won 4 skins @$1/ea x3=$9+(2) sleeves of PRO V1 golf balls from the Pro Shop. This was the 3rd hole, during our Wednesday HUMP LEAGUE, and we started on the back side due to course renovations.
