Michael Taylor, I'm sorry I don't have any more pictures, nor, do I know the distance from the current back tees. Also, I highly doubt the USGA had any input on the impetus for this change. This change reeks of the PBC. As to your last post, a thinly hit shot will not get out of the bunker.
Tom, I'm sure most pros will try to get short and left of them, but, even a pro misses. Early in the round, one may not have figured out how heavy the air is yet, or, how firm the canvas is, and, how and where they are hitting it, that day. Either way, if the justification for this type of bunker is to be penal, the rough was just about as penal as you could get, for the shot demand to this green, making these bunkers anything but penal. IMO, it makes the shot easier.
