spdb,
My neck of the woods for the past 5 years has been Ann Arbor, I'm in the process of moving to Chicago.
Indianwood is one of the great 36 hole complexes around. I'd even choose IW over Oakland Hills (for 36, not 18).
The new course at IW is a typical "BIG 80's" course, lots of contrived mounds, really tough, forced carries, etc.. I'd say it looks like Jerry Pate was trying to create his version of the bear in SE MI. It's a little over the top at times, esp from the back tees. Not my favorite, but a strong 5. Like Nicklaus I think Pate has gotten better over time and if brought back could make this a lot better (softer).
The Old course is really cool. As I said before, think mini Shinnecock. It plays fast and the grasses give the place a stunning look in the summer, otherwise I think the aerial speaks for itself. Number 4 in the lower left hand corner is wonderful, the tee shot plays into a hill and the second shot is semi-blind, playing to a green that is similar to what is found at NGLA.
