The buses fired up early Friday morning and social media was flooded with the obligatory first day photos as Dawson County students headed back to school. Almost 3,400 students in pre-k through 12th grade were enrolled to begin on Aug. 5, according to Lisa Miller, who is the district registrar for the Dawson County Board of Education. "It has been a great first day in Dawson County Schools," said Superintendent Damon Gibbs.
