Southeast of Troy the road lifts toward Averill Park and Sand Lake, and the snow totals climb right along with it. Rentz Lawn Care LLC plows and shovels through that country and back down in the city — driveways, walks, entries, with salt and sand wherever the grade turns treacherous. In the warm half of the year it is mowing, trimming, edging and cleanups, week after week until the mower finally goes quiet. Higher ground means a longer winter and a later spring, and the schedule respects both ends of that. What does not change is the finish: even grass, open pavement.
