Book excerpt: For the past 16 years, Cadillac Man (so named because he was once hit by an El Dorado and thereafter bore an imprint of its hood ornament) has lived on the streets of New York City. Over those years, he has recorded the facts of his daily life - the harsh realities of surviving on the street, the often tragic encounters with the non-homeless world, the deep bonds with his fellow homeless, and the surprisingly varied realities of life on the outside - writing hundreds of thousands of words in a series of spiral bound notebooks. "My Life in the Streets" distills those journals into a memoir of homeless life that is peopled with indelible characters and packed with gripping stories. In a gritty, poignant, and funny voice, Cadillac narrates his descent into homelessness, the travails and unexpected freedoms of his life, and the story of his love affair with a young runaway, whom he eventually (and tragically) reunites with her family. The United States has 700,000 homeless people; ultimately, Cadillac's story is their story.
