Steve Vaught is walking almost 3,000 km across the USA from Southern California to New York City.

He says he wants to lose weight and regain his life, and is documenting the journey on www.thefatmanwalking.com

Inaccurate maps, encounters with interesting people and a knee injury have meant that the trek will take longer than the expected six months. Though he cannot know exactly how much weight he is losing, as there are few scales on route, he says the walk is a life-changing experience.
