Patrick,
There are a number of photo's of NGLA in Ran's profile, and the overwhelming majority appear to show a rugged, natural-looking course, a far cry from that convex hazard. I have never seen a sand dune that looks like that thing. Is that what you are comparing it to? A sand dune? really? Seems like a stretch.
From a strategic standpoint, seems to me like an awful lot of architects have found ways to create blind shots without utilizing a convex bunker. In Ran's photos, the image of the first hole, where a bunker sits at the base of a large mound, would serve that purpose. Sure would be better than the eyesore that currently guards the green. It is so out of place, it even manages to distract from the spectacular view of the water.
