Walk

Now nearly halfway through his trek, Alan Christoffersen walks from South Dakota to Memphis, Tennessee. He covers more than 800 miles on foot, but it's the people he meets along the way who give the journey its true meaning.

Alan Christoffersen loses his wife, his business, and his home and embarks on a cross country walk, leaving behind what little is left of his life, and in the course of his journey, the people he meets and the places he visits offer him hope, inspiration, and refuge.
