Where Routes 11 and 100 cross in Londonderry, the West River is still young enough to be noisy, and the valley opens just wide enough for fields. M Waldo Landscaping keeps the lawns in that opening — mowing on schedule, trimming around foundations, posts and garden beds, edging drives and walks back to a firm line, and clearing the yard out in spring and again in fall. South Londonderry's steep dooryards and the flatter lots near Lowell Lake want different handling, and both get it. A well-kept lawn in this valley is a small piece of order held against a lot of mountain, and it shows from a good distance off. Londonderry, South Londonderry, Weston, Peru and the neighboring towns are served.
