South of Somerset Street the ground begins to climb, and it doesn't stop until it's the Watchung ridge looking back down over the roofs. CHAMPION'S LANDSCAPING works that grade the whole year. Winter means plowing and shoveling and salt, hill driveways opened early enough that the commute stays only a commute. Summer means mowing, edging, string trimming and carting the clippings off, week after week, so a yard never quite gets away from the person who owns it. The pleasure is in the contrast — a January dawn with the town white and silent, a July one with everything green and already growing back.
