There’s a “creed of nomadic freedom… lurking like a low-grade fever in the shadows of the American dream,” says Richard Grant. In Aeon Magazine, he traces it from the bison-hunting braves of the Great Plains to the RV-driving pensioners of Arizona. (Grant’s latest book, by the way, isn’t Crazy River, as a note on Aeon says; it’s Dispatches from Pluto (Simon & Schuster), in which he gives up his own wandering — though maybe temporarily — after falling for a plantation house in Mississippi.)
