Regarding the 12th, the trees on the left are close to the fairway, but I was not aware the property line is so close to the fairway. The back tee tend to aim toward the left,and more width on that side would create an approach from a poor angle. At Rustic, and probably all of Hanse's designs, there are holes designed to lure you into playing away from the optimal approach. The 12th at Kingsley has that potential if the fairway were expanded to the left
By the way, I think Kingsley is a superb course, but believe that Rustic is a more sophisticated design. And as I stated earlier, the greens complexes are truely great!
