Looking Google Maps of my local town and the nearby motorway this morning, every road was either closed or orange/red/dark red. And that was with all of the schools in the town and the surrounding areas closed. If people had been trying to get to school on top of that, no one would have been going anywhere anyway.
But yeah, whenever the schools shut due to weather anywhere in the South (even though it hasn't happened for a good few years now) is because Southerners are such pathetic fannies
