In Jericho the last light of the day comes down off the west face of Mount Mansfield and lies flat across the hayfields before it goes. That is the hour Avalon Sunset Tree Services likes best — mower shut off, the lawn holding its stripes, the edges clean along the walk. The green months here mean mowing, trimming and cleanup work in dooryards tucked between the ridge and the valley floor. Winter turns the same route into plowing and shoveling, headlights swinging into driveways that climb toward the hills. Either half of the year, the pleasure is the same: a property that looks cared for from the road.
