In Palos Verdes, on the northbount descent of Hawthorne there's this sculpture on a stone pillar in front of an apartment building. I suspect that the demented person who put it there is a cyclist him(her)self.
Notice the shoes -- apparently after this "incident" they peeled the cyclist off the bike and left his shoes.
Hawthorne can be a pretty speedy descent. This could be interpreted as a warning....
