The irony is that it's the 'Dark Ages' only for those same kind of well-travelled-and-rating-inclined golfers as the ones who originally compiled a list of 'America's 200 Toughest Courses', for Golf Digest in the 1960s.
One of Ran's mid 60s antecedents worked to ensure that courses like Firestone were featured on that list, and his many acolytes agreed with him and celebrated its inclusion; but some 40 years later, after assuming the mantle of golf's enlightened man, Ran himself, now come of age, looked back at that time and those tastes with utter contempt, and consigned both his ancestor and the list to darkness and oblivion -- leaving only the acolyte-types alive and intact, ready to (lemming-like) follow their new leader.
Meanwhile, far from the centres of power and influence, in the flung-away places of the world, average golfers by the millions who were immune to the influence of conventional wisdom and indifferent about expert opinion played (and continue to play) literally thousands of modest and low-key and unknown golf courses designed & built during these same so-called Dark Ages -- the vast majority of which are c. 6100 yards long, and feature the wide fairways and gentle contours and open-fronted greens that allow for strategy and recovery and the ground game, and that make them playable for all levels of golfers.
So, the 'Dark Ages'? No -- no, for millions of average golfers like me there was and is no such thing. We are happy, in our ignorance, to simply play the game of golf, humbly accepting a golf course for what it is instead of always complaining about what it isn't. But for the cognoscenti of the world -- then and now, determined to stamp an era with their own seal of approval or disapproval -- they see precisely what they want to see, and hope to convince the rest of us that they are right!
