Just think Adrian if they invest in a lake they may ask you to come up with one of these two design options
With the added feature of a fountain which only works when the ball fall into the hole.
Or perhaps that is just as ridicules an idea as scaring a course with lake and associated fountain. Oh yes more money can be raised by renting out boats, fishing permits, bathing, - oh hell let’s just call it a country club and forget the golf.
Silly no, is just as practical as having a lake and fountain on a golf course.
