15th at Harlech. 435 yards into the prevailing wind with trouble everywhere (but no bunkers)
As discussed on this site before, this is one of those holes (and Harlech is one of those courses) where 'bogey' in the traditional usage makes much sense than 'par'. Many of the holes cited in this thread would have had a bogey of five, at one time (not least of course The Road Hole itself).
