David,
I think those are examples of courses ON the ocean as opposed to courses close to the ocean.
Trump's LA course also fell victim to landslides, as do many of the residential developments.
But, if you consider courses offset from the ocean but close enough to enjoy the ocean breezes, you still have to ask why there's a paucity in quality courses.
I know many bashed Sandpines, but, I felt that there were a number of good holes at Sandpines.
Could it have been better ? Sure, but, I don't think it's as bad as many, including my friend Tommy Naccarato claim.
Tommy and I have had many discussions on Sandpines and I'd like nothing better than to play a round with him at Sandpines.
Could it be that the architects felt that anything they produced would be enhanced by the quality of the views ?
