In 1933 Alister MacKenenzie said about St. Andrews TOC, "I doubt if even in a hundred years' time a course will be made which has such interesting strategic problems and which creates such enduring and increasing pleasurable excitement and varied shots." We have a decade left to prove him wrong.
Is it possible that this undulating, wrinkled, rumpled, crumpled land is THE key element, especially on inland courses, and that when this essential subtle ingredient is missing, courses can be too flat and dull and uninspiring? MacKenzie said that these undulations on fairways and greens are the key to variety and variety is everything. Maybe in our ham-handed modern machined way, we have been making them, as Tom points out, too big and dramatic and clunky.
If making wrinkled land throughout the entire course is either too boring for a shaper, equally as or even more complicated to get right then shaping a bunker or a green, too expensive, too easily wrecked by maintenance equipment, etc., no wonder we don't see it much except on courses where it's natural or in a sacred places like St. Andrews where it has been left alone.
What if it really were to be much, much more complicated than it looks to get it right? Leaving it to a random throw of marbles is an interesting solution but perhaps the wrong way to recreate natural random links ground made by wind and rain and the elements. Just leaving it to a crewmember works if it's really not too hard to accomplish.
Maybe the answer, at least for the time being until we learn to do it inexpensively, is to use 3d printers and automated vehicles to recreate the folded micropatterns from ideal course land. CBMacdonald would also probably like to know we are still trying to recreate ideal landforms and a "wrinkle in time" 100 years later.
