There is an hour in Parsippany-Troy Hills before Route 46 wakes up, when the salt trucks have gone by once and every driveway is still a blank page. A L Services Inc works that hour — plow down, headlights out front, the blade laying a clean shoulder of snow along the asphalt so a car can back out without a second thought. By the time the coffee is on, the walk is bare to the concrete and the mailbox is reachable again. In the warmer half of the year the same trucks come back for mowing and edging, cutting a straight line along the curb where lawn meets street. It is small work, done early, and the whole street can see it.
