At three in the morning the Jackson Road corridor is nothing but falling snow and the amber wash of a plow light. Colarossi Landscaping Co. runs snow removal through Scio Township on those nights, opening driveways and lots so the first car out at six meets pavement instead of a wall. Walks get shoveled to the step, salt goes down where the melt will refreeze by dawn, and the piles get pushed where they will not block a sightline. Michigan storms rarely quit when it is convenient, so the work goes on until the last approach is clear. Colarossi Landscaping Co. plows Scio township and the surrounding stretch toward Ann Arbor, Dexter and Chelsea.
