I mean, its easy to figure out why he hasn't played them. I mean, he plays on the tour 20ish weeks a year, plus travel. He rarely plays a tournament on South Florida (and used to live in Orlando, no short drive) and I am not sure if he has ever played a tournament near Philly. It may just be that with the way he practices and the events he plays, and his corporate committments, he simply doens't have time to go wandering off to play other courses.
Ask him if he's played Sand Hills, Ballyneal, or Shadow Creek. I'd be he hasn't. He practices at home and goes to events. I just wonder where he will join to practice in Jupiter, I'm sure Jupiter Hills would love to have him.
