In A Race to the Bottom of Crazy, Grant mixes memoir, research, and reporting in a quest to understand what makes Arizona such a confounding and irresistible place. He visits the world's largest machine-gun shoot; takes a sunset boat cruise with a US Congressman and a group of far-right patriots; rides through the desert with a Border Patrol agent; and goes camping with his family in breathtaking mountain ranges that rise out of the desert like islands in the sky. Interspersed with these adventures are recollections of his previous stint in the state, including his friendship with cult writer Charles Bowden and years living off the grid with smugglers, dope farmers, and outlaws on the Mexican border. Ultimately, Grant arrives at the conclusion that Arizona has always been a scattershot improvisation, with bizarre and extreme behavior in its DNA.
