Book excerpt: Secrets. Sigalerts. Ravines. Records. In Paperback L.A., A Casual Anthology Book 3, our contributors deftly command fiction, nonfiction, playwriting, magazine writing, memoir and other forms to conjure up visions of a Beverly Hills Wonderbread factory, the founding of the first sustained gay rights organization in the country, early 20th-century wagon-train settlers in Dodger Stadium area, a late 20th-century DTLA traffic tie-up that becomes a kind of symphony, a humorous 1940s novelty song whose refrain buoyed civil rights activists, the 1990s outrigger-team apprenticeship of a Tongva youth—and more. Plus, photo essays on “Motion and Stasis,” “Hometown Gold,” “The Right Notes,” and “Nowhere.”
