This St. Louis motorcycle policeman looks happy, and why not? He gets to ride around all day on this big, black Harley with flashing lights all over it, make a lot of noise, bust bad guys and protect the citizens of the city (at least in theory). People get out of his way. He gets to drive real fast sometimes. No wonder he's smiling.
It's gratuitous cuteness, Chinese division, on St. Louis Daily Photo.
