The trash on the Venice boardwalk sparkles like Wet n Wild lip gloss. This is what people forget about Los Angeles beaches: They're part of the city, inundated with the city's grit. Half-melted Icees in Styrofoam cups, one flip-flop, taco foil, condoms, a dead vape pen. Needles. But also: a Swarovski crystal earring. A pinwheel unmoored from its handle. A streak of gooey glitter. Coins of many lands. A few miles up the Pacific Coast Highway, away from the skateboarders and homeless people, WASPs sun themselves at country clubs as employees sweep the sands.
