Would MacK have considered RMW 18 blind?
Blindness was accepted back in the day, because it permitted a routing maximising 'pleasurable excitement' . Without the option of knocking down hills, golf would have been very dull if golfers had always expected to see instantly the results of their shots.
Curious thing about 5 at Prestwick, was it there to get to the sixth, or because the designer (Old Tom?) thought 'that's a sporting shot'? Did he seek it out, or was he stuck with it?
With the old gear, getting it up and over such a formidable hill and then down again to the green was a 'shot of the round' for amateurs
