In 1914 Henry Ford and naturalist John Burroughs visited Thomas Edison in Florida and toured the Everglades. The following year Ford, Edison, and tire maker Harvey Firestone joined together on a summer camping trip and decided to call themselves the Vagabonds. They would continue their summer road trips until 1925, when they announced that their fame made it too difficult for them to carry on.

Although the Vagabonds traveled with an entourage of chefs, butlers, and others, this elite fraternity also had a serious purpose: to examine the conditions of America's roadways and improve the practicality of automobile travel. Cars were unreliable and the roads were even worse. But newspaper coverage of these trips was extensive, and as cars and roads improved, the summer trip by automobile soon became a desired element of American life.

The Vagabonds is "a portrait of America's burgeoning love affair with the automobile" (NPR) but it also sheds light on the important relationship between the older Edison and the younger Ford, who once worked for the famous inventor. The road trips made the automobile ubiquitous and magnified Ford's reputation, even as Edison's diminished. The automobile would transform the American landscape, the American economy, and the American way of life and Guinn brings this seminal moment in history to vivid life.
