Undoubtedly, the most under-rated golf course in metro Detroit, featuring many stand-out holes, including:
--the Redan-esque par 3 second (!!!);
--the par 3 fifth, which plays over the aforementioned ravine in dramatic fashion (!!!);
--the short par 4 seventh (!);
--the par 4 13th, where there once was a dual fairway presenting a neat driving option over a diagonal creek (!!);
--the par 3 fourteenth (!); and,
--the par 5 seventeenth (!!).
Oakland Hills South is a nice treat every once in a while, but I'd prefer Plum Hollow if I had to choose to play either or, everday. In fact, there are very few other courses in the Detroit area (besides, perhaps, Franklin Hills) I'd rate higher in that category.
Properly restored, Plum Hollow should feature on Golfweek's list of 'America's Best' Classic courses, IMHO.
