Wow, a Par 4 hole in one! Congrats!
I got mine back when I was 13 at the Radium Resort course. I believe it was hole 12 and just a par 3. 7 iron, landed about 2 feet in front of the cup and just rolled in. Besides my foursome there were two groups waiting behind us, everyone went nuts. It was awesome!
I have the ball, hole flag, and letter mounted on a nice wall display.
