At Ahu Tanga Te'e you can see seven or eight thrown over Moais. In front there are a few Pukao, the red stone hairdo's of the statues.
In front of the Moais you can see a little sign which says: "Get of the grass, or......" or "Cut of the grass, or......"
I just can read it right anymore. C'est dommage.
We had a French guide.
