Was there any friction between Ross and Mackenzie during their glory days? In reading Ross's Golf Has Never Failed Me there was a caption stating something along the lines of Ross's bunkers were superior because of placement and did not feature unnatural fingers, etc in building them (excuse my lack of identifying the exact caption, traveling and don't have the book on hand!).
They must have crossed paths often...were they bitter rivals, did they share ideas, what was their relationship like?
