I noticed, but thought they looked more Scottish so they are okay.
Its an inside joke. Back when Jeff worked with me, he did many of the plans for Champions Run in Omaha. For variety, I had sketched in a cluster of bunkers by a green to break up the standard look. From memory, I then went to Singapore for a week and when I came back, Jeff had added them to several other greens and a few fairways to boot.
I borrowed a line I heard from Jim Colbert about the TPC greens. Jim was on the Tour players committee that worked with Pete, and he had told him "That first green, with the hump in the middle was fine. The problem is, you liked is so well, you did it 17 more times!" I had the same feeling about the cluster bunkers showing up more than once or twice.
I will try to alter my schedule to make the event at TAMU. Got trips to MN, outlying Texas and maybe China to accomplish in that general time frame. Then I would be on the "Blume Trail" having just played Grand Pines a few short weeks ago.....
