The Joy of Yes

This is my reward for braving afternoon traffic on the 101 and the 80 in order to say 'yes' to my son's request to drive home from SF across the Golden Gate Bridge.  These rainbows have been here as long as I can remember, although I don't know when they were painted or whose idea it was.   Anyone?
All I know is they make me happy whenever I see them.
