Ian,
Nice pics on Twitter. I'll need to keep an eye on future #courseoftheday posts.
I don't think the course has changed much since Wilson built it in the late-50s. Here's a (bad) picture of his original routing plan.
Note: Though this plan shows that Wilson originally conceived of 15 as a par 5, it was not built that way.Other than being over-treed, I am at a loss for how the course could improve without compromising its original character. Changes, for instance, which reconfigure the bunkering in certain places, would increase the variety of shots that you need to play but might also feel out-of-place.
I feel very strongly about preserving the work of Golden Age architects. I believe that courses designed and built by one of the masters, eg. Mackenzie, Macdonald, Ross, et al., merit preservation, restoration, and study. In an ideal world, greens committees and architects would refrain from attempting to improve these classic courses by carrying out unnecessary modern renovations. (a necessary change would be one induced by changing realities, eg. liability concerns...)
I'm not sure that I feel that Dick Wilson's work is in the same league, though. I could be wrong but I associate him with with architects like RTJ, Sr. and George Fazio.
I guess this brings up an important question... Do fine Dick Wilson courses like Deepdale and Meadowbrook fall into the same category as the classics from the Golden Age? Should these clubs also be discouraged (equally strongly) from making changes which are not in keeping with the designer's original plan?
