Carl,
How right you are.
Some years ago I played with a fellow member, Dr. Benjamin Dowdey, on the Old Course. A very good player who missed qualifying for the Briitish Amateur at Muirfield in 1990. We got to the 17th hole and I asked if he had ever hit on the green and holed the putt. He replied "No but Idid hit on the green and had a two." I believe it had been done but once before, way back in 1926.
I mentioned this to Sid Matthew and it's in his book, "Wry Stories on the Road Hole."
I am not sure if the R&A had even asked for his card.
