I think it's a bit narrow-minded to view the bunker as one architectural feature and the rough around it as another. To me they're one and the same, and just as one section of a bunker can be less penal than another, or just as some portions of rough in the same area can be thicker than others, not all portions of the same bunker + hazard are created equally. James, I think the equation "bad shots should not be rewarded" is too simplistic and deterministic...is there no place for luck in the game?
I do have a problem with neat and tidy bunkers with perfect sand and easy escape routes which are surrounded by gnarly rough. You do occasionally see this type of bunker at the US Open and, especially, at certain PGA Tour events. If there really is a huge advantage to be gained from being in the bunker instead of the rough, that's as much a maintenance meld problem as an architectural one, and it needs to be addressed. However, the RCD bunker I see in the picture has difficult rough around it *and* a high lip which, combined with its distance from the green, makes it less than easy to escape from sand. I don't think it applies in this case.
