Mark, Jeff --
Maybe we can agree that both of you, along with all those who share your tastes, find the 'contrast of elements' beautiful and attractive to the human eye, while many others, including me, find that same kind of contrast jarring and unpleasant, and prefer to see the blurring of those elements because it looks more 'natural' and pleasing to the eye.
And in regards to the word 'natural' itself: I think we all know and recognize that we are playing a man-made game called golf, and that none of the elements we find on a golf course designed to facilitate the playing of that game -- the greens, the fairways, the bunkers, the tees, the drainage basins -- are 'natural' in the sense that they are naturally occurring or that we see them in/recognize them from nature.
Not a single person I have ever met, when using the word 'natural' about a golf course, has meant the word in that sense, ie as if he were talking about Yosemite or the Tongass national forest or the Rockie Mountains or the Mojave Desert.
Instead, what we mean by and are referring to when we use the word 'natural' is the relationship of/between those many elements one to the other, ie how they blend into each other with the flowing (instead of fixed) and time worn (instead of static) and native (instead of cultivated or transplanted) qualities of nature.
It's those qualities that I look for and appreciate. When human hands can manage to create an aesthetic for a field of play that is flowing and time worn and native -- as if that golf course has been there and part of the landscape for 100+ years -- that is quite an accomplishment and testament to skill and talent, and to my eyes it is also very pleasing and beautiful, even as simply an expression of the art-craft at its best.
