Tommy:
As you know, Sand Ridge was not built for tournament play, but I believe it would be capable of holding a US Open. Facts to consider:
1) The course could be set up to play between 7,200 - 7,300 yards.
2) The greens can easily be taken to the 12-13 level on the stimpmeter and provide all the putting challenge one could handle.
3) The blue grass rough could be maintained at a level lower than typical USGA set up standards (say 3.5 inches) and still provide a very strong incentive for accurate tee shot/iron play.
4) The golf course sits on 365 acres and has plenty of room for 30,000 spectators. The only major logistical problem would be the two bridges over the wetlands between #11/#12 and #15/#16.
5) There would be plenty of room for corporate tents, though the modest clubhouse facitilies would require some adjustment.
6) There would be ample space for nearby parking.
7) The course is near a major metropolitan area capable of the necessary hotels, restaurants, etc.
Overall, Sand Ridge has most of the things needed to host such an event and, for better or worse, could be set up in a manner the USGA traditionally prefers. An Open qualifier was held at Sand Ridge a few years ago. The low round was 69; average score was 77.
Do not, however, look for Sand Ridge to be considered. I do not believe the membership would look kindly on the hassles associated with such an event.
