Montgomery County, Maryland, is quite prosperous, but wishes its school buses to make more than two runs per day. So the high school students are out at the curb early in the morning, since nobody wants the elementary school students out in half-light. The high school students--who would prefer to sleep in--are groggy from lack of sleep, the elementary school students--who wake early--have an extra hour at home to do nothing in particular. I don't know what the story is with the middle school kids.

I commuted to college long ago one winter with DST. I did not enjoy it. I'm not sure I'd have enjoyed it even living on campus.
