First light lands on Norumbega Mountain long before the fog lets go of the lowlands, and the birds start in while the grass is still grey with dew. Mountain Wren Tree and Garden Specialists begins the day in that hour, mowing and trimming lawns around Mount Desert while the air is still cool enough to work hard in. Turf under the mountain's shoulder gets thin sun and thick moss, so the cutting is careful and the edges get read by feel as much as by line. By the time the fog lifts, a yard that looked rough at dawn reads clean and deliberate. Seasonal cleanups keep it that way, needles and leaves carried off before they mat the grass down.
