oak, i think you've been toking too much, there is no way any professional, no matter how many times they have played a course, even from the womens tees that could shoot a 53 on beth page.
i've been playing golf all my life, i'm in my 60th year of playing "real" golf, played on a weekly basis with professionals, the best score i have ever seen posted was a 63 on a course that was the publinks national course, called eastmoreland in portland, oregon. the player was the pro there and played the course on a daily basis. believe me, eastmoreland is no beth page.
