The office parks along the I-88 corridor go dark by seven and stay that way, acres of empty asphalt waiting on whatever the night decides to bring. Dirt Pros Excavating LLC works those hours in Lisle, plowing lots and drives, stacking snow where it won't block a sightline, and salting ahead of the dawn refreeze. There is a quiet pride in pulling in at four in the morning and pulling out at six with the pavement black and the walkways down to bare concrete. Nobody sees the work; everybody sees the lot. That is the job, and it gets done before the first car turns in.
