Tom,
I think you would agree, restoration of a course that is “tired” which I define as one that is just not conditioned well, greens have shrunk, bunkers reduced in size or left fallow or grassed over, grassing lines altered,… is very different from restoration of a course that has been purposely changed and bastardized. There are times when I get to a course and it takes months of research to figure out what was once there and how it evolved. In the case of the latter, the improvement via restoration/renovation could be fairly dramatic. One example was Berkeley CC which we just played at the ASGCA annual meeting. It is night and day from what happened to it to where it is now. You would not have known what was there and how good it could be without doing the research. Just my opinion.
