There are many great lights in the San Francisco Bay area that Harbour Lights has yet to do that would make a great series.
Point Bonita with it's suspension bridge,
East Brothers Island, beautifully restored.
Fort Point under the Golden Gate
Mile rock as it used to be
Yerba Buena Island
Farallon Islands
Oakland Harbour
Of course we already have Alcatraz.

What a great series this would be!
Point Montara and Point Reyes are close enough to be considered Bay Area as well.
