Richard...I would say that, at Longaberger, he was probably handcuffed by two entities: the wetlands and the corporate wags who wanted a killer course.
I found Bay Harbor to be incredibly fair. The Links (which is not really a links) has the best and only downhill Redan I've ever seen...number four, I believe. Unfortunately, I found the staff to be a bit pretentious, but that has nothing to do with GCA. The par five, number seven, was incredible...you felt like Columbus, heading to the ends of the earth. It was too bad that they had to use a piece of inland (better suited for the quarry or preserve nine) terrain for their ninth hole, a jungle beast if there ever was one. I also found the quarry nine to be quite fair, despite the forced carries on a few of the holes. I felt like the ball on one of those little plastic games where you try to get the ball to spiral up the cone, round and round, into the hole at the top. The whole nine laid itself out beneath you; you knew that eventually, you would reach the floor, then ascend again. I did not play the preserve nine.
The AH course at Boyne Mountain was also incredibly welcoming, challenging and memorable. I believe that for overall worth, I would rate Longaberger third of the three Hills courses I have played. I would place Bay Harbor at the top, with the Boyne Highlands course a half-notch behind. Longaberger was a great course for me (4 or 5 handicap who plays the tips on most courses) but not for lesser players.
