The old highway north of Springfield runs dead straight through this stretch of Sangamon County, past grain bins and farmhouse windbreaks, and the lawns along it sit on some of the blackest soil in Illinois. Pristine Lawn Service works those yards in the early hours, when dew is still down and the mower leaves a line you can read from the porch. Grass grows hard here from May onward, so the schedule stays tight and the deck stays high enough to keep roots in shade. Edging, trimming around posts and bins, then the walks cleared, the small finishing that separates a mowed yard from a finished one. On a June evening the whole property reads as one calm green rectangle in the middle of a working farm county.
