How does this routing work, except for both sides opening with par 3s? Though I don't think the view from the clubhouse wold be something to write home about.
Front Nine: 16, 17, 8, 9, 1, 2, 3, 4, 5
Back Nine: 6, 7, 18, 10, 15, 14, 11, 12, 13.
I tried to start a nine hole loop starting with 14, but couldn;t come up with a satisfactory flow.
