Inspired by “Doomsday Prep for the Super-Rich,” by The New Yorker’s Evan Osnos, Patricia Marx gets herself ready for the apocalypse. The only problem: Marx is a writer, not a Silicon Valley mogul. She isn’t super-rich, or even regular-rich. Apocalypse prep on a budget, Marx discovers, is a whole other ball game. Plus: “I’m a Proud Nuclear-Missile Owner”—written by Teddy Wayne, and performed by Nick Offerman—takes the right to bear arms to a whole other level.
