Not sure if there's a more recent thread, but I saw in today's Crains Chicago Business that there's a review of the course. 8100 yards, course rating 80.0, slope 148. Greens fee of $350.
"An average day sees just two or three dozen guests, a result of high prices and the exclusivity that management is trying to promote."
What kind of course can stay open for long with that kind of business model?
