If we abolished DST, the sun would rise in northern Minnesota around 3:30am and set at 8:30pm... nobody lives on a schedule of 3:30am-8:30pm... an hour later is nominally better.
But to push it back so that kids are walking to school in the dark is just not a good idea.(yes, we're not in the suburbs where sidewalks are rare and walking much too physical, so children actually have to walk to school if they live anywhere from 1-2 miles from the school building).
It rises that early up there? Seriously. Wow, even during the summer time the sun never rises before about 5:45 am and it sets at about 9:15pm here. The winter the sun rises about 6:30isAM standard and sets about 5:45ishPM.
