Not sure how this thread got pulled from the depths of the archives, but glad it did.
When I think of mysterious golf courses, I don't necessarily think of a ton of blind shots. Like the old saying, it's only blind (mysterious) once. After one play you have unlocked the secret.
When I think of mysterious courses, I think of places like Augusta, where everything breaks toward Rae's Creek. I think of Rustic Canyon where all things run down the canyon. I don't remember the specific hole, but in Tom Doak's "Anatomy of a Golf Course" he lays out a scenario where the ideal line is closer and closer to a bunker...then the player resetting because they don't want to hit it in the bunker. To me that is mysterious and why certain places make ideal members clubs. It takes multiple plays to unlock. Places where rangefinders make no difference, because they don't hit the shots.
