Sean,
Nearly all of my courses could easily be par-70s — especially in today;s world of 480-yard par-4s. At the c. 1928 Adobe (Arizona Biltmore) which opens next month, we renovated and wound up with four par-5s all in the 460 to 510-yard range. I feel it an easy change to make the course a par-70 and simply change the scorecards...but the evil golf professional staff lurks nearby and so, too, the marketing gurus. They will have none of this. It is not politically correct.
