Up on the hillsides above the borough the lawns tilt, and mowing a tilt well is its own skill. Grasshopper Lawns Inc takes Naugatuck's slopes in the cool part of a July evening, when the heat lets go and the crickets start up in the tall stuff along the property line. Cutting height gets set for the weather, edges are held true beside the driveways, and the clippings never end up in the road. Beds are mulched, shrubs kept in shape, and the autumn cleanup runs until the last oak leaf is down. A hill lawn that reads level from the street is the whole point.
