Mark,
Yes, work has started. Last Fall, Mike DeVries and myself, along with the Sunningdale crew, did work on the 11th green and fairway, 12th tees and green, the tees on 13 and the green on 14. We also added a new back tee on 15. We intend on being back out there this coming Fall for another section of holes to work on.
There was a thread back in December that had some pictures on it. I may try to find it for you, but you may be better at using the search function on here than I am.
Joe
