"Can you spare some change?" Dirty, smelly, talking to themselves...that's how most people think of the homeless, if they think of them at all. You probably never stop to think of the homeless as real people, to wonder where they came from or what their lives are like. In her first book, Living in the Shadows of Milwaukee, Laura Marsh shared her personal experiences of being homeless. In her new book, On the Trail, she and her fiance have gotten off the streets and into an apartment, but she continues to observe their lives and those of their homeless "family" from the perspective of someone who spent many years living on the streets, a.k.a. "on the trail.""
