It is important to always be observant. One of the reasons I love San Francisco, is that it is a compact place and very easy to get around in by walking. One sees a lot more on foot than from inside a car. You can never tell what you might find if you look.
For instance, I have always suspected that there are things about the Far East that Westerners don't understand, and I think this picture from a recent walk through Chinatown proves it....
