If I had ten rounds to play in Ann Arbor;
7 U-M Golf Course (MacKenzie/Maxwell)
2 Barton Hills (Ross)
1 Radrick Farms (Dye)
Also, I caddied for Nicklaus in his inaugural round at Wabeek in the summer of 1973, which is indeed a Dye/Nicklaus co-design from approx. '71-'72. Truth be told, Wabeek is a co-design of Dye, Nicklaus and Chrysler Realty. Most of the work appears to have been Chrysler Realty.
Edit. -- Sean's right about what a magnificent piece of property Radrick Farms is, and could have been. It is the old Matthei family estate, adjacent to the University of Michigan Botanical Gardens, which was also a Matthei family bequest. To his credit, Pete Dye graciously came back to Ann Arbor to have a second look at Radrick, and he refined a fair bit, including a fair bit of tree removal. I just can't help picuturing Tillinghast on this large and amazing property, creating another Bethpage or SFGC...
