Damn, my first ever and only one! It happened at Ventura, California during 1st annual Lake Casitas Classic tourney in 2004. It was pure lucky shot. After 1st round, I went back to #16; 261 ft; to practice my shot where I had twice O.B. that hole in first round. At teepad, you couldn't see the basket because cattails were so high in front of teepad that you gotta throw it little high hyzer or anhyzer, impossible to do straight shot unless your height at 6'5". So I threw my 175g tye-dye Champion Orc with my girlfriend watching me. As we approached the basket, we didn't think to look at basket first. We looked everywhere on ground. The porta-potties was about 50 ft away from basket. One guy came out of porta-potty with unzipped and unbelt short as he seems like tried to get out of stink booth real quickly to take a look or just in rush. After unfortunately find my disc, I looked at guy, and his looks like he just saw a ghost. He pointed at basket, as I turned around, and shock in awe. I told guy, he must have picked and throw it in basket to make it look like I aced. He said no kidding, I said oh @&#^, my first ever ace. I laughed at guy so hard after telling me as he was about to do his #2, and heard WHAM! He hold it and came out to take a look. That was so damn funny.
Been almost 3 years drought and still going dry. I need other ace real badly after had many close calls last year.
