TD, I can understand the idea of wind blowing the bunkers in erosion and loosing lips crumbling more into the greens. But yet, in 12 years at Wild Horse on the closest design style of bunkers abbuting greens, #15, as far as I know - they haven't lost green surface. Ditto #8 greenside b at Sand Hills. But then, I am not there to see the yearly progression of any preventative measures that the supers may have to do.
I'd go with soil and roots of couch-bermuda as a bigger factor, off top of my head. Also, as explained by Mr Clayts, wind isn't so much of a rare ocurrence in their area.
I wonder if Mike Nuzzo's Wolf Point may be one of the most conducive sites to emulate OZ bunkers?
