Kingsley was recently rated #37 in a new category by Golf Digest called something like "Best 100 Golf Retreats". This indicates the course's overall rating is improving greatly. I'm quite sure it will move into Michigan's top 10 (maybe 5) next time. I don't think #37 on the golf retreat list corresponds to an overall U.S. top 100 rating, though.
I played there with a GD rater last year and he liked the course very much. I think it's a wonderful golf course, with as many truly memorable, unique holes (especially 2, 4, 5, 13, 15 and 16) as any I've seen. I think the course is short but difficult, requiring great precision. I do not find the course to be as aesthetically beautiful as some of my other favorites, but the course yields so many great shots to play. It's a great place, plus the weather is super sweet up there in the summertime.
Tommy W: #9 is my least favorite hole on the course for two main reasons. First, the hole requires a short to mid iron of extreme precision, exactly the same challenge presented at hole #2, which I like better. In either case, a bogey is a good score if one misses the narrow target. Second, the hole is a damn tough walk for 165 yards, down into a deep valley before a steep walk to the green. You can walk the cart path, which is longer but less severe.
