Roanoke-CountyThe World is not your ashtray..that’s the slogan and message Roanoke County is sending with a new anti-littering campaign launched this morning. It focuses on people who throw their cigarette butts out of car windows. County residents will be able to report on line if they see someone tossing cigarettes – those people may get a form letter from the police department. The Roanoke County Board of Supervisors passed several resolutions in November that made the anti-littering campaign possible; it includes bill board advertising and temporary road signs.
