Ira,
When I compare the current batch of work to what was being produced 100 years ago it seems very hard to see the distinction. When you compare the work of Ross to Raynor, to MacKenzie, to Tillinghast, to etc... they are all very different. While the philosophy on play might have been very similar, the look, feel, and style of their courses were much more distinct. That is something I, and I believe others in the golfing world, are not seeing in much of the work being produced today. The distinct designs of the courses from the golden age have been significant in their longevity and it is in the uniqueness of their design that the great courses of the world have in common. We talk about places like Pine Valley, The Old Course, and Oakmont so favorably in part because there is nothing else like them in the world.
Was it only after time that the great courses of yesterday showed themselves to be unique and distinct, meaning that evolution will occur with the courses of today, or was their just a greater breadth of design styles that produced a broader range of work than is going on today?
Ben:
I agree with you that design today is not as diverse as it should be.
But it's unfair to compare a period like the 1920's, when there were hundreds of courses being built each year, to today, when there are less than fifty per year. When the business is big, more architects get chances to try their stuff, and there is more impetus to try new ideas in order to attract attention. [Ten years ago, there was plenty of room for Mike Strantz and Jim Engh and Tom Fazio and Rees Jones in addition to the minimalist camp.] But when it's small, like now, many firms [and many developers] get conservative and stick to what's been successful and is already drawing attention. [You could say the same for movies today.]
Your sample is also pretty lop-sided. MacKenzie, Ross, Raynor and Tillinghast were all working in the 1920's ... but then the courses you cited were Pine Valley, Oakmont and St. Andrews, none of which were built in that time frame nor by any of those architects! If you are expecting new courses to rival those, you're probably going to be disappointed.
At the end of the day, though, the only architect whose work I can control is my own, and I think the courses we build are pretty diverse. The rest of your wish list is up to others.
