South and east of the square, Sigourney's ground breaks into the timbered draws that run down toward the English River, oak and hackberry holding hillsides a plow blade can't reach. Sigourney Tree Care spends its summers up in those same limbs and its winters down at ground level, clearing the driveways that wind back into the tree line long after dark, once a storm has finally let up enough to run a truck. Snow falls differently under a canopy than it does in the open — it catches in the bare branches first, then lets go in heavy clumps long after the square has already been plowed clean — so the last driveways cleared some nights are the ones tucked back among the timber. There's a rhythm to finishing a hollow drive by headlight, the blade throwing a spray of snow against dark trunks, and coming back the next morning to find the lane still holds its edge. The same ground gets worked two ways across the year, and both times it comes down to letting the trees and the hillside decide what a driveway can be.
