You have to really love San Francisco to appreciate a movie like this... It's a celebration of a bit of wreckage out at Point Lobos.
Back in the late 1800s, Adolph Sutro (soon-to-be Mayor of San Francisco) bought a huge tract of land by the Pacific Ocean, developing and selling it a bit at a time. In the '90s, partly as a public service, he opened the Sutro Baths, a swimming place with water at various temperatures for various people.
But it was much more than that. Sutro's incorporated several museums, eating places, and much more. It was a huge entertainment/amusement complex that burned down before I moved out here and is just, well, a ruin today.
There's a lot of footage of various people talking about their experiences, a lot of footage of the place itself, including the final fire: it's a documentary for lovers of San Franciscana and pretty much nobody else.
I enjoyed the heck out of it.
As a bonus, one of the filmmakers (Tom Wyrsch) was present to answer questions. Also present was Ernie Fosselius, whom I had the chance to meet and talk with and who signed me a copy of Hardware Wars, making my day pretty much complete.
