For Mark Walker, cutting hair out of a beat up van in the projects of East Nashville is not just a living, it represents a much larger dream. Even while battling homelessness, a wife upset with his lack of money, and property owners upset with his van locations, Mark has an undying optimism. He preaches of RVs at every street corner with red carpets unfurled, barbers, beauticians, nailers -- the whole package. Mark keeps the faith alive, and that there will always be another corner with another head to cut.
