Atop a big rock in the Pacific Ocean at
Sunset Cliffs is the site for a changing metal sculpture. In early 2006 it was a big metal pterodactyl. By June 2006 it was a multi colored metal peace sign. It is a mystery who puts these sculptures on the rock, and even more or a mystery is how they do it. It's likely the sculpture is installed at night, as during the day it would be hard to do anything in such a visible location unnoticed.
