If we stayed on Standard Time throughout the year, sunrise here in the Chicago area would be between 4:15 and 4:30 am from the middle of May through the middle of July. And if you check the times for civil twilight, which is when it’s bright enough to see without artificial light, you’ll find that that starts half an hour earlier.
This is insane and a complete waste of sunlight. Good for a nation of farmers, I suppose, but of no value to anyone in our current urban/suburban society except those people who get up and go running before work. And I see no reason to encourage them.
