I played there MLK weekend.
We took caddies, but carts are always cart-path only at all time now. Don't remember what the forecaddie policy was for cartballers. Although why anyone would want to cart on #2 I'll never understand. Cartballer members slowed the pace of play down all day. We had a 3-ball member cartball group in front of us and waited on every hole. A nice, tight 5+ hour round.
If you walk you must have a caddie. We were going with double bag caddies but because they had an excess of caddies that day, they gave us each a caddie for no extra charge.
All areas are now considered waste area. Two years ago when I played there they distinguished between bunkers and waste area. Any bunker that was completely surrounded by grass was considered a hazard. Not sure what facilitated the change but they just made everything a waste area.
The changes seemed to have brought a renewed interest to the course, and the reduction in water use has surely saved money. Our caddies said they will water the fairways in the spring as the bermuda comes out of dormancy, and then after that they let nature dictate the playing conditions (and turf color) and don't water except in extreme weather circumstances (which we have not really had here in NC since the restoration). That's why the turf was a nice brown during the US Open last year, and in late-July/August was a dark green because of all the rain during that time.
