That one is fenced off, isn't it?
Matthew:
A good question, but you'll probably be disappointed in the answer, which is that our associates usually have more time to get back to the courses they worked on than we do.
Think about it. I'm on the road +/- 150 days per year for work. I've designed 30 courses all around the world. And there are other good courses to see, too. So, I'm lucky if I can make time to visit 5-7 of my own in any given year. [Random sample: last year I went back to Cape Kidnappers, Stone Eagle, Pacific Dunes, Aetna Springs, Apache Stronghold, Rock Creek, High Pointe, Beechtree, and Sebonack. But it's been years since I saw Quail Crossing or Barnbougle Dunes.]
Now think about Jack Nicklaus who has designed 300 courses, and is working on 20 per year. Jack's associates go back to those courses occasionally, I'm sure, but he only goes back to play in an event or when they pay him to look at redesigning something; although he did stop in and play Sebonack with someone last year.
I do have some experience with looking at one of my old courses which isn't being maintained well ... but even then, what am I supposed to say? It's the owner's course; I can't really complain that they are making me look bad. I will certainly offer our help when asked, but I don't want to be a nag ... and to tell the truth I would really prefer just to play the course and enjoy the day instead of nitpicking little details.
