The quick response is never. I've played fifteen different courses this spring. Ten of them have had significant work done in the past five years, one of them is planning work and the other four would like to do some things but don't have the money. Is it just the nature of the business that tinkering happens throughout the life of the course or does there come a time when clubs just say, "We have the course where we want it." We all bemoan what's been done to classic courses in the fifties, sixties, and seventies: planting trees, adding runway tees, etc. I realize that greens need to be regrassed from time to time, length can be added here and there, and bunkers need constant care, but when can we say, "Enough already."
