And now that I'm on this line of thought:
When was the last time any of us has even HEARD of, let alone seen/played, a new course that at some stage in its development/routing ever had a CHANCE at turning out to be a Par 64, or Par 67, or Par 75?
I mean, with hundreds and sometimes thousands of acres of land, how is it that architects have NEVER seen that the BEST 18 holes were ALL Par 4s? Or on less than ideal/large sites, how come we've never heard of an architect that decided that the land didn't offer even ONE Par 5 that was worth a damn, or that the land dictated EIGHT Par 3s?
I mean, motion pictures are pretty conventional as well, tending to be in the two hour range, but at least we have evidence, say "Heaven's Gate", that a filmmaker at least once REALLY believed that he needed FOUR hours in order to tell his story best.
Where and in whose filing cabinet is to be found even one initial routing that DIDN'T turn out to be between Par 69 and 73?
