first hole in one at member member tournament

This year at member member with my 16 yr old son as my partner. We played 16th hole at Tillery Tradition, a 235yd par 4. I was playing my usual pro v1 golf ball and I used my 20deg. Hybrid to hit off the tee. I picked a line over a green side bunker right side. I swung with great rythem and watched the ball fly over the trap, bounce once and disappear. We get close to green looking for ball and I notice group in front of us coming back towards our green? I told my son they must have forgot a club?? They were coming to see who hit that shot!! They saw it go in. I went cold all over and ran to see ball in hole. My first hole in one!I
