I just ran through my last round at Ballyneal and recounted how many tee shots I didn't see finish. Holy smokes, I didn't expect to come up with so many.
2, 3, 6, 7, 10, 15, 16.
That's quite a few. So many in fact that maybe there's a less obvious question to be asked here. How many times can an architect ask a player to hit the ball but not see the results of the shot? The relative greatness of BN isn't in question. So it appears that a private club where member play is the overwhelming norm can afford to have more blindness than a public course. Using another great course of Tom's as example, there's really only 2-3 blind tee shots at Pacific Dunes. It stands to reason that the one-time retail player probably wouldn't enjoy a half dozen or more tee shots that they don't know if it's good or not.
