The Bodie ghost town
In 1880, Bodie was California's thirst most populous city. In the 1920s, terrible weather (100mph winds, monthly frost) turned the mining town into a near-ghost town. In 1932, a massive fire left it totally deserted. The people left but more than 100 buildings remained, including the general store, Methodist church, saloon, bank vault, and cemetery. Now, Bodie is a National Historic Landmark and state park, where for $5 you can explore its state of arrested decay.
