Joe:
We did restore the routing of three holes at San Francisco Golf Club, as Jim mentions. However he failed to mention that it was a very divisive change at the club, and there are still at least a few prominent members who continue to disagree with it, 6-7 years later. The change had been made so long ago that we were destroying the golf course as they had always known it, history be damned.
From your question, I think you are referring more to where a change was made to accommodate new practice facilities closer to the clubhouse. I've seen changes like that on a handful of courses in the past 30 years, and it always seems to create controversy, because in every case the new holes that replaced the old ones (to make room for the range) were deemed not to fit in seamlessly with the rest of the course. The only club I know of that did the work and then reverted to the old holes is Rochester G & CC in Minnesota, a Tillinghast course which Geoffrey Cornish had changed. I believe that they changed the course back for good, although I haven't been back since to verify that.
