From Carville to Playland-at-the-Beach, the savvy San Francisco historians at the Western Neighborhoods Project have documented it all. When Barbary Coasters ruled the alleys and barrooms of the played-out northeast, all of western S.F. was once a giant sand dune, an undiscovered haunt of farmers, recluses, and beach lovers. Learn the location of the surviving 1906 earthquake shacks and private railway tracks that made the city that was on the WNP's exhaustive website, stocked with rarely seen photos of long-lost local treasures. Then visit WNP's human troves of knowledge in person at one of the regularly scheduled talks, including a seminar on how to learn the history of your own home, or a bicycle ride through living San Francisco lore.
