Tell me again about the par-four finishing hole at Sebonack...
There's a big difference between a client bringing up a different idea during the design process vs. when the course is finished. Sebonack has examples of both, actually.
I had no problem with Mr. Pascucci requesting the 18th hole be a par-5 instead of a par-4 ... we just had to sort out whether there was enough room to do it. He brought it up during the clearing phase, so there was plenty of time to weigh the choices and figure out how to make it work.
By the same token, I was not a fan of the changes made to the 14th green after the course was completed. But, it's Michael's course now, so he gets to do what he wants with it.
I guess I've been luckier than some architects on this score, but we all work for clients with minds of their own, so it's bound to happen on occasion.
