Kirk,
Circular shapes of sand do not occur in nature. But in all the times I have spent on links courses they have not appeared as unnatural.
I agree completely. That's what starts to get to me as the whole subject of "natural vs. unnatural" in golf course design is discussed. I've read a number of Tom Doak's posts on this subject, and I think he has a very specific idea of how he wants his courses to interact with the land they occupy, and I really enjoy reading those posts and looking at his work and seeing how his philosophy is made real upon the ground.
And yet I personally am not repelled by bunker shapes and tie-ins between course and surrounds where such efforts as Tom Doak's were never envisioned or attempted. Again, I think this issue tends to revolve more around personal taste and expectations than it does any kind of immutable law.
Andy, you bring up the notion of context, and context is in many ways the crux of this issue. It is within the context of the golf course that those round shapes seem to bug you, while the fact that there's a bunch of incredibly closely-mown grass around that is not often found in nature doesn't bother you, or the rest of us, at all. It seems perfectly natural to see all that short grass.........on a golf course!
The shapes created at the Castle course may bother Melvyn more on that bit of farmland where it was built than they would had they been created close to the sea, where tie-ins to the surrounding land (the context of the course) would more closely approximate reality (or am I off-base on this, Melvyn?).
I would posit, Anthony, that the "purity" of a golf experience, or the lack thereof, exists more in your own mind than it does anywhere on any golf course.
And Kalen..........well said.
