Bedford still has dirt lanes and riding trails threading between its pastures, and on a late-August evening the dust hangs gold over them long after the last mower shuts off. Leos Tree & Lawn Service Inc keeps the lawns along those roads through the whole growing stretch, from the first flush of May to the brown-out weeks of high summer. Mowing, trimming around posts and fence lines, hedges tightened up, mulch refreshed where the rain has thinned it. The best sign of a good day is a fence line cut so evenly that the eye follows it straight to the barn. Come November the same crews are back for the leaves, and the yards go into winter clean.
