The one time I played Chambers in the summer of 2010, the alternate green was used on the 5th. When I stood on the elevated tee box, I immediately saw the original green in the distance and had a wow look on my face by how cool it looked. Then I noticed a little sign on the tee box saying we were using the green on the left. Who doesn't like a short par 4 right. I hit a good low draw about 20 yards short of the green, when I approached the green, It sort of had a Ballyneal #7 approach look going on how it was tucked in between two dunes moving to the left, the greens are obviously not at all alike, but the approach was somewhat similar. I am sad, I thought it was a cool concept. I am always a fan of options.
I have a picture of the green somewhere I will try to find it.
