On the east bank of the Penobscot, where the river runs wide and dark past Eddington's stands of pine and the back roads bend toward Clifton, Grasshopper Lawn Care LLC spends the green months keeping the grass in good order. There is a plain satisfaction in it — the even stripe laid down across a river-valley yard, the edge cut clean along a gravel drive, the trimmings gathered and the lawn left breathing in the long northern light. Summer here is short and generous, and the work follows it closely, from the first flush after mud season to the leaf-strewn quiet of a Penobscot County fall. Come evening, when the mower falls silent, a tended yard holds the whole day's care in its crisp lines.
