Mark,
Nice for me too. I would think that, as with this course, bunkers tended to be placed (or replaced) very close to the green to make the course play harder when the aerial game came into more play. In today's game, it seems likely to me that bunkers 10-20 yards away from the green might be out of play. In the example I came across, that was done later, apparently in the early 60s.
Kyle,
A couple "set back" bunkers are located directly in front, zipping across most of the green 15-20 yards from the green. Otherwise, most are to the sides, usually front left or right.
Tyler,
That could be (though R.B. Harris also practiced this a bit in the 60s). Are you aware of other classic courses where this was seen?
