Ran,
I suspect that Bill McBride has touched on, what seemed to be basic routing 101, employed by the classic architects.
Club house location was an integral part of the routing process, opening holes didn't go to the East, nor closing holes to the west, though there were exceptions.
Nines had clock and counter clockwise movement, and direction changes were abundant.
I've said it before, somewhere in time, there was a departure from, a disavowing of, and a disassociation with classic design principles. Individual creativity became the rage, ignoring many of the design tenets established and passed down over the ages.
I don't buy the "no more good sites" theory.
Are we to accept that only locations near the old, big cities were good sites for golf courses.
Does GCGC sit on a good site, or a plain piece of property with a little roll ?
Can you find sites as good or better than GCGC, I say yes, in abundance. When GCGC was first opened, roads traversed the property, and the town today still has easements through the golf course.
I will say that environmental issues have been a major impediment in building, designing and routing golf courses.
One can't fault architects for inheriting those very difficult and very real problems.
The question is, would the owner select a less troublesome site, had they known all the environmental problems up front ?
The short answer, ego, and denial of legacy have been the biggest contributors to losing the art of routing.
But, that's just my opinion, I could be wrong
There is a new course being built on the North Fork in Long Island. One nine loops counter clockwise, the other clock wise.
Both nines tee off to the south, one nine ends northwest, the other to the east, both nines start and finish at the elevated clubhouse, with about 13 or more directional changes. Plus, Plus, Plus, there is a good deal of wind that influences the site.
It seems like a pretty classic routing to me
Fortunately, few environmental problems hampered design.
