Was reading Mike Bell's book "The Golf Courses of Stanley Thompson" and found the following in the section titled "Recollections of Thompson's Driver" by Garry McKay - page 142.
(John Parkinson was Stanley's driver in the summer of 1947)
-- Because he was a teenager that summer, Parkinson didn't really appreciate the genius for whom he was working. It wasn't until his later years that he came to understand why Thompson and his golf course architecture are held in such high esteem. Parkinson said much of Thompson's talent was that he could visualize. He remembers clearly one such example when he and Thompson were deep in the woods at the base of the Niagara Escarpment in Hamilton. As they walked through the bush, Thompson pointed out a knoll with a stream running away from it. "He said he thought it would be a beautiful par three, straight down the river, and when the river bends away, you would have the green," Parkinson recalls. The next day, they were back on the same spot, and Thompson asked Parkinson to pace off the potential hole, telling him he thought it would be about 150 yards, and ideal length for a par three. "I paced it off, and he was right on," said Parkinson. "He could visualize ti and see it and sense it as a hole."
