The worst storms in this part of Morris County begin as rain and quietly become something else after dark. JB's Landscaping runs the plow through those nights, clearing driveways and walkways and laying salt where a wet afternoon has turned to glass. Snow removal is what the outfit does, and it does it on the storm's schedule rather than anyone's convenience. There is a plain kind of pride in a drive that is already open when the porch light comes on in the morning — no shovel leaning by the door, no guessing at the bottom of the hill. Mount Olive gets its share of that weather, and then some.
