Carol Stream was drawn on flat prairie and built for work, and its business parks fill with trucks before the sky has picked a color. Summer here means the long green margins along loading docks and office drives — mowed, trimmed and edged week after week, so a plain acre of pavement gets a soft border. Then the wind swings around to the northwest and the same ground is measured in inches instead of blades: plowing the lots, opening the aprons, salting the walks so first shift never breaks stride. There is a particular satisfaction in a parking field cleared corner to corner while the town is still asleep, nothing left behind but wet black asphalt and a straight windrow at the curb. Commercial grounds are a year-long conversation, and this one gets answered on both sides of the calendar.
