Andy,
Dave and I just played there last week. Some exciting things will be happening soon at OLCC, think CHAINSAW. The current bunker work was done by Art Hills so prepare yourself to find your ball up against the lip if you happen to find a bunker. My understanding is that Mr. Hills has claimed that he screwed up on the bunker project here, I credit him for that admission. I wonder if he'll refund the clubs money? The bunkers are also on the docket for a total redo, the super thinks that the faces will be restored.
Anyway, OLCC is a fine course my favorite holes being 1,7,8,11, and 13. I'm not sure what a true C&A course should look like so I can't comment on how true it is to the original design. Without question it is much different today though. The C&A courses I've played are Century, CCofDt., Plum Hollow and here. I can't draw any strong themes from them probabaly based upon the redos they've had. You will be able to notice some of the filled in bunkering that would add much character if the club approves the restoration.
Orchard Lake is a fine club, the club's super A. McMaster does a great job and really "gets it", say hello to Kenny in the shop too.
