This week Kurt Andersen talks with Alex Gibney, whose new documentary follows Ken Kesey and The Merry Pranksters on the road trip that launched the psychedelic 1960s. Then we ride the economic roller coaster with novelist Gary Shteyngart. His novel Super Sad True Love Story imagined a debt crisis that feels all too similar to the one we’ve found ourselves in recently. And a respectable middle-aged couple ditches Houston for Buenos Aires when they fall hard for tango.
