At five in the morning on M-52 the plow lights swing across empty parking lots, and Manchester is still a village asleep on both banks of the river. T & N Service Inc works that hour, plowing, shoveling entryways and salting the walks so a door can open safely at seven. The rest of the year the same properties get mowed, edged, trimmed and cleaned up on a steady rotation. Southern Washtenaw County swings from April mud to January hardpack, and the work bends to whichever it is. What stays constant is the finish: nothing half-cleared, nothing left ragged.
