Mike,
I know of at least a half dozen Tilly courses whose members believe that a specific par-3 on their course was "Tilly's favorite" among all he ever built... For decades the tale of Sam Snead walking off Bethpage Black during a 1940 exhibition match against Byron Nelson because he believed the course was "too hard to play" has been echoed on to all who stepped foot on the property. Of course that Snead set the course record on the Black 2 years BEFORE his Nelson exhibition and that the newspaper accounts showed that he & Nelson tied in match play with Snead again tying his own, even-par record score while Nelson shot the first under par round on the Black with his 70, somewhere got lost in the sands of time.
Unfortunately, even though many clubs have fairly good and substantial records going back to the days they were founded, many, many do not. We should never be surprised when incorrect understandings of a club/course past is revealed...
