Most of us probably know where this photo was taken—on Colorado Boulevard, at the Glen Iris crossing. We can also tell what's going on in the background—something most of us love to hate. And I'm sure many readers even know exactly who's the white-shirted gent talking to the Bureau of Street Services employee in this photo. If you happen to be one of those readers, the challenge isn't to disclose the man's identity. Rather, it's to be as cryptic as possible without giving away the actual name or other aspects of his identity.
