Late August lies heavy on the Mad River valley, and grass grows fast in the days right after a mountain rain. Classen's Tree Service works the lawns and grounds of Campton through that green rush — mowing, string trimming around ledge and root, hauling the cuttings away, keeping beds mulched and squared. Look up from almost any yard here and the humped ridges of Welch and Dickey stand above the treeline, which is a fine thing to have over your shoulder behind a mower. Come autumn the cleanup is a long slow sweep, leaf by leaf, until the lawn lies bare and even and ready for cold. The work is plain; the setting is not.
