I can't answer your question, Matt - but in reading about many of the golden age American courses that are considered great today, it is amazing to note that the vast majority of them were considered great the day they opened. How can that be -- unless the principles of great golf course architecture haven't changed in a 100 years? (That's what I assume to be true). And yet, many of those very same courses - great then, great now -- have been tinkered with continually, for decades, sometimes in a one-step-forward-too-steps back kind of way, suriviving through successive green committees and tastes and economies. So something 'essential' must've been there that could not and has not been altered, I assume. And what is that? Ah, 'upon what meat do these the golden age classics feed that they have remained so great?!"
