Played here 4/05/12 the starter wrote my name down wrong, so I waited an extra hour before teeing off. The greens are in the best shape I've ever seen here, rolling about 10 1/2 to 11( very fast). The fairways are always a bit thin in places, especially on the back nine. There is quite a bit of maintenance on the back nine dealing with drainage issues. Over all a good long track with greens that you can putt. This course is one of my regulars.
