Mark,
I think you are right about that and I know that The Country Club did the same on one of their holes, at least for the practice found of the U.S. Open.
Noel,
I would often get the post-round phone call.
It begins with, "I can't play golf anymore."
Followed by "I don't know where my irons are going."
Then onto, "The green complexes are ...., the par 3s are... etc."
Finally, "I have a lesson tomorrow, I hope I can work this out."
