Art,
I recommend touring some of the private clubs in lieu of playing, if that's not heresy. (Of course, I have seen you play!
Tom Gray is the super at Frankin Hills, a nearly untouched Donald Ross, not far from Oakland Hills. He is an old friend of Eric Nelson, who works with me.
I have toured several others, but have never actually played in Detroit, as I usually visit my mother in Toledo early spring. I have played two Brian Huntley courses, including one in Monroe, which have some holes worth studying.
