San Francisco is a city of neighborhoods and within its seven-by- seven mile boundary it seems every patch of ground has a name. In this episode Joseph explores six of the city's famous, little-known and changing neighborhoods in search of what distinguishes them from the rest and makes them must-visit San Fran attractions. He learns that each has a unique history and iconic attractions, shops and restaurants that add their special zest to the San Fran mix. He finds neighborhoods where people in the mist of change are working together to not destroy what they have, but make their neighborhood more what it is. The song says, "I left my heart in San Francisco" and the city has more than 800,000 residents and millions and millions of visitors who have left at least a piece of theirs here - and Joseph discovers that he is one of them.
