Jeffrey - interesting that you and Tom mention Crystal Downs. I have only played it once, and while undoubtedly a great golf course, for me it had more "artifice" than art to it; in short, I don't think of it as "stripped down". Much like Augusta (the only other Dr Mac course I'm familiar with, but only through hundreds of television viewings), I found the "planning" of Dr Mac's work very evident there, very "conscious/self-conscious" for lack of a better term. Perhaps that is why my favourite holes at CD, besides the Par 5 8th -- which is the only Par 5 I've ever loved -- were the Par 3s: there was something remarkably understated and stripped-down about their design and presentation, i.e. they "work" and fulfill their purpose beautifully, but without -- as, for me, many of the famous Par 4s seem to do -- drawing attention to their architecture/strategy/choices.
Earlier in the thread Tom mentioned The Loop -- and from photos and write ups, it seems a course that, in part because of its reversibility, has been stripped down to it essence, both in terms of its playability and with its aesthetics; I imagine that any "artifice" there, any strikingly-evident and obvious "design", would stand out like a sore thumb....if not from one direction than certainly from the other.
I asked earlier if Ian had worked (while with Doug Carrick) on Ballantrae , a course north of Toronto that I played (many years ago) several times. On the one hand, you couldn't find a more quintessential housing/real estate course -- I imagine the routing was directly tied to/had to take into account that component; but on the other hand, I remember it as an excellent example of a particular kind of stripped down and low-to-the-ground and understated golf course...and I remember how much my friends and I (ranging from a 4 handicap to a 18) enjoyed it and found it playable and commented on the quality of the design, years before any of us really thought about architecture. (Years later, it occurred to me that it was the closest I'd yet come to playing something akin to Garden City). If Ian DID have something to do with the design, it shows that his appreciation for such apparent simplicity of intent and design is of long standing.
