Ummmmm, maybe it's not just about whether or not there's ice on the roads??!?
There may not be ice, but a lack of ice on roads doesn't mean all danger from ridiculously cold temperatures is removed. I for one don't want ANY child to have to be on the side of the road waiting for a bus for any length of time when it's this cold. Additionally, a two-hour delay would give faculty and staff a chance to arrive at the schools and check to make certain water is flowing. It's entirely conceivable that pipes could have burst, rendering our schools dangerous and not up to code if there's no running water for toilets, fountains, or cafeterias.
