I had originally seen this sign about two months ago, when we were driving in somebody else's car on the way back from skiing. We didn't stop then, but driving by the same place again last weekend, I just had to stop and take a picture of this! Somebody had altered this sign with a bit of black tape. There is another one about 20 minutes down the road that was done much more cleanly (which I think was the one I originally saw).
We also visited the Rakaia River Valley and the site of "Edoras" from LOTR. Edoras is Mt. Sunday (the small rocky hill in the foreground) and looks just like the scene in the movie. It was really windy the day we were there, you can see the grass all pointing the same direction.
