I like it as a quirky feature (primarily on older courses), but agree that it can get out of hand. I think it's a dosage-related phenomenon. My Exhibit Number one is the Bayonet course at Fort Ord. I only played it once, but the cant of the fairways (usually a negative camber), provided the principal defense to the golf course, making it play way longer than its posted yardage. I don't know if they sent the earthmovers in to alter some of the fairways in the relatively recent renovation, but it wouldn't have been all that bad of an idea. Olympic, as mentioned, is another course made extra tough because of this feature.
