As Mr.Ambassador is not quite up to par, I decided to re-investigate ST. A's # 5 and the famous course marker thereon. My earlier investigations indicated said marker was probably hollow in nature, so I set out to obtain proof. In this un-retouched photo, you can see from the divots in the lower right corner, it took me two tries to chip my ball inside the marker.
The set up for the next shot clearly shows the ball has dissappeared. What's more is, I'm sure these results can be duplicated, so I am pleased to release my findings to the community at large.
Doc :)
