"There is, one knows not what sweet mystery about this sea, whose gently awful stirrings seem to speak of some hidden soul beneath..." That's a quote form Moby Dick, but it could probably be the backstory for many who once left the land for the vastness of the ocean. 

Of course not all who took to the seas returned from them, and in those instances, what's left behind are the broken and battered remnants of another time. There's a long history of ship wreaks in the San Francisco Bay Area. So all this past week, those relics of the past were brought into focus with ship wreak week in San Francisco.  

For a more of the background of the genesis of shipwreck week, KCBS Radio's Mary Hughes spoke with Nicole Meldahl, executive director of the Western Neighborhoods Project, and James Delgado senior vice president of Search Inc., and former director of NOAA's Maritime Heritage Program.
