This is a MUST SEE. Extensive interviews with SF Transportation Genius Emiliano Echeverria, author Mike Phipps, and gripman Val Lupiz. I don't agree with the theory of the origin of municipal ownership of transit in San Francisco, nevertheless, the film hits on all the important events in cable car history. Did you know, in fact, that Chicago once ran a much larger cable car system than we ever did? So much information I may have to go again. The Balboa has held over the presentation for a bit so call the theater for times.
