If you are passionate or even interested about the history of San Francisco, California, or specifically the history of the Cable Car, which began there, you would enjoy this book. It is filled with technical details from how much it cost to build, run and maintain them up until the 1940s, to the exact routes they ran. Sprinkled in are personal anecdotes from and about the people who began them, as well as some of the early luminaries of San Francisco. The focus is more on the cable car lines before the Great Earthquake of 1906, but the book includes that and how most of them were closed down by the time this book was published in 1940. ( )
