I guess I was lucky, as the upper-end course near Vegas where I had my one and only hole-in-one mailed me an awesome plaque for free...commemorating the occasion.
Nice art drawing of the hole, the date (4/5/04), the club (8 iron)...and yardage (161 yards).
A bonus was that it was a nice, flushed, high-draw shot...and we watched it disappear.
