6 am deadline to call off classes and notify local media, and the fact that the previous advisory predicted plenty enough snow to make driving dangerous, and that prior releases noted the northward trend may require expansion of the warning, many superintendents, including those of Douglas County Schools, Cobb County Schools, Marietta City Schools, Fulton County Schools, DeKalb County Schools, Decatur City Schools, Cherokee County Schools, Paulding County School District and Gwinnett County Schools, failed to cancel school until it was too late. Some superintendents apologized, including those for Douglas and Atlanta, while Cobb superintendent Hinojosa refused to acknowledge his failure, and even went so far as to claim that he "wouldn't have done anything different", despite students being stuck on school buses for hours, and some having to spend the night in schools. Even more students were stuck in Cherokee, a northern exurban county to which the warning was not extended until later in the morning, but still well before students were actually released. Gwinnett schools failed to release students early at all, and was spared only by the fact that the snow and dropping temperatures arrived slightly later on the northeast side of the metro. DeKalb schools staged buses outside schools, and thus had very few students stuck. South-metro counties correctly called off classes before they began, avoiding issues entirely. Buses became stuck not only due to slick roads, but even more so because traffic in metro Atlanta (except the east and southeast) quickly ground to a halt between noon and 1pm, as shown on TV by traffic-speed maps from GDOT's Georgia Navigator system. Complete gridlock ensued, preventing the area's few snowplows and other road-treatment vehicles from getting anywhere. Tractor-trailer trucks became stuck on the Perimeter (Interstate 285), essentially closing the bypass route around the city. Other trucks, normally banned from inside the Perimeter except for local deliveries and pickups, then went through town and became stuck along with other traffic. At least three babies were born on the roads, including one delivered on I-285 by a Sandy Springs police officer who was having his own birthday that day, and whose daughter was born when the Great Blizzard of 1993 hit Atlanta. Another was born with nobody other than the mother present. Along with the Georgia State Patrol (GSP) and Highway Emergency Response Operator (HERO) units, the Georgia National Guard was called out to deliver supplies and rescue
