There’s a new documentary on the way about the most famous Mexican themed roadside attraction in the United States: South of the Border. “S.O.B. and the Legend of Alan Schafer” will premier Saturday, April 25 at the Charleston International Film Festival. The film examines the life and stories behind Alan Schafer, the heroic figure behind this world famous attraction. Hopefully the film will put to rest some of the rumors and mysteries about Pedro.
