Although, this discussion, along with the pictures of the Medinah redesign really have me thinking about a property that has recently changed hands.
The Rabine Group purchased a far NW Chicago club, Bull Valley, which includes a 37,000 sq foot clubhouse for $1.7M. The land, IMO, has better bones than Medinah #1 did (although the surrounding development, which isn't in play on most holes, would probably prevent as dramatic of a rerouting). Now ignoring the fact that it's likely silly for a "golf only" club to have a 37,000 sq foot clubhouse, with that modest outlay, and the bones that exist, I would think if you could bring in a Doak or a C&C, and turn it into a top notch club for a reasonable cost, you'd be able to pull the additional members needed to make money (or have a great destination resort for day trips from Chicago).
