Wednesday afternoon, firefighters from Mar-Mac, Dudley and Arrington responded to a working structure fire behind a residence on Arrowhead Lane off Genoa Road. Black smoke could be seen over the treetops as the fire units approached the scene. The firefighters found not one, but two structures fully engulfed in flames. The quick action of the fire departments brought the blaze under control and kept it from spreading to a nearby living structure. According to officials at the scene, the fire was caused by a nearby burn barrel being used to burn yard debris out behind the buildings.
