Weather announces itself here from the northwest, over the first Watchung ridge, and you can watch a Westfield sky go flat and low a good hour before anything falls. CH-Hilltop Landscaping reads that hour and starts moving — trucks staged, blades down as soon as there is something to push, driveways and walkways opened, salt worked into the ice that forms in the shade of a porch. On the high side of town, where wind stacks a drift against a garage door, that means coming back a second time and a third. In the green months the same properties get mowing, edging, trimming and cleanups on a schedule so nothing gets away. The hill gives you the view; it also gives you the work.
