Admittedly I do not quite share the same sentimental attachment to golf that many on this board do. That being said, records fall in just about every sport (where athletes/teams are not competing head-to-head) often over time.
For the most part athletes in every sport (golf included) are better trained (mentally & physically), have better technique, better equipment and better playing conditions than ever before. In addition, professional golfers come from a far wider pool of participants than ever before. Scoring records in golf will continue to fall.
The big surprise is that 37-year old the scoring record at Riviera has yet to be broken.
