I think it's the logistics of getting a million + students on the move that has them avoiding any morning-of calls. Because of the scheduled end time of 4-5 AM and marginal temps I was telling my wife and son all weekend he'd have school. I hate to play armchair mayor, but this was a mistake. When you remember how many hundreds of thousands of kids are dependent on being in school for their meals, how many parents don't have the ability to just stay or work from home, it's is hugely disruptive.
