Up on Cobbs Hill the reservoir path fills with walkers the minute the ice lets go, and every lawn on the streets below seems to wake at once. Advantage Lawn Service Plus llc works that awakening — mowing on a set rhythm, trimming the fence lines, edging the walks, hauling off the leaf drifts that pile against porch steps in October. When the first hard squall crosses the city, the same trucks turn to plowing, salting and cutting a path from the door to the street. There is a plain pleasure in a striped lawn in July and in bare blacktop in January, and both belong to this job. Rochester asks for range, and the answer here is simply to show up in either weather.
