I've got a suggestion:
How about if the left side bunkers on #18 were moved into a catch-basin, similar to the right side of #16 at Mid Ocean or #2 at NGLA . . . . . or even the left side of #16 at NGLA???
Let us say you put a splash bunker down on the bottom of the *pit* on the left side of #18; how interesting would it be to watch professionals try and approach the green from the base of a pit with only sky to guide their approach?
Imaginine the commentators describing the ball tottering down the pit on the left. . . . . .
Mackenzie would be proud.
