Joe:
Pretty sure they put the pin in the swale more than once a month. They've already had two or three aces on that hole, and they probably weren't to the front or the back.
I played so well on the Red in my matches the other day, but I choked on this shot, just after telling our group that I had always been freaked out about Bill's choice to put a hole here, thinking only the very front part of it was going to be used for the green ... it just looked like an impossible shot to me. And, of course, they had the pin in front for our match, so I fanned one into the water. Luckily my partner Fred Muller had already hit one to 8-10 feet.
Also, when we began construction, the area down to the left of the green was a canal that was used to transfer water into the big lake from down along #17 fairway.
