Chris,
Are you evaluating ANGC's bunkers based on TV and photos or personal observation ?
In person, the bunkers are anything but "cookie cutter"
As to their "whiteness" remember, it's showtime in April, and the contrast of the white sand and the green grass makes for high contrast, colorful viewing.
Clubs that don't televise their golf course, that choose ultra bright white sand, do so of their own volition, and it's the leadership of those clubs, not ANGC that should be taken to task.
