Rob, the old bunkers were very shallow and indistinguishable as to size and shape. It would have been a stretch to call them hazards. I do not believe, however, that the white sand is anything new. While I am not entirely sold on Weed's style, from a playability standpoint, the new bunkers are head and shoulders above their predecessors. FYI, #16 was the only spot I saw where things were clearly overdone.
Michael, as you note, the site is a tough one. The routing is what it is. Its not going to change. So potential for improvement is largely limited to bunkers and greens. While I am not convinced they fit aesthetically with the rest of the course, there is no doubt in my mind that Weeds work is significantly better than what was there before.
