The elusive ace. I've come within inches 3 times, back when I played better, so now it will be luck. Probably one that will bounce off the Goodyear blimp.

My cousin has two on the same hole. 100 yards, up hill, severly sloped green. You can only see the top quarter of the flagstick. One of the aces he drilled into the hill and it hopped up on the green. Unfortunately on that hole you can't see them go in.
