Well see I, like many, have a job. If I leave by 5 pm and get home by 6 pm, its pretty much already dark. This also provides the added bonus of driving West with the fucking sun setting in my face the entire time. I also love driving to get to work by 7 am with the fucking sun rising in my face the entire time.
Additionally, multiple studies have shown that kids do better with a later school start. That would resolve the "think of the children" pearl clutching about them having to travel in the dark. All that is left are the whiny pussies who act like they can't wake up without natural sunlight - they can buy an alarm clock and grow the fuck up.
