Is there room to stretch out CPC, if they wanted, to make it a challenge for the pro's? If so, would the longer course still be great?
I would have to imagine there would be room to stretch out CPC, because you have to consider what Augusta did. They bought land from a neighboring golf course, they picked up and moved entire holes, they moved complete existing on ground facilities such as the putting green. I hope no one is short sighted enough to take these kind of steps at CPC. The only thing truly more flexible about ANGC is the wealth that makes it possible to flexiblilze, (vandalize?) the golf course.
Furthermore, making ANGC longer made it less great. When you move a bunker to put it in play for the pros, you take it out of play for the vast majority of your golfing clientele.
