Shaun MacMillan, left, and Rick Swanson, of Island Fire Protection, dash to douse a grass fire with chemical extinguishers. Seven grass fires erupted next to the E&N Railway line Wednesday from Northfield Road to Dorman Road, possibly due to a passing freight train shedding sparks into tinder dry grass in the railroad bed. MacMillan and Swanson happened to be delivering a truckload of fire extinguishers to a customer when they came across one of the fires.
