Summary: Alan Dein meets the evangelising travellers of Edinburgh who live amid the decaying remains of the city's Craigmillar estate and worship in the Life and Light church. Once a thriving community, today Craigmillar lies two thirds empty, with promised re-development on hold. Venturing into the heart of a housing scheme rife with drug dealers, according to the travellers, Alan is not sure what kind of reception he will receive. Producer: Kate Bissell
