By the middle of July, the side streets off Central Park Avenue hold their heat long after the sun has dropped behind the ridge. Azteca Landscaping Ny works into that stillness — mowing on a steady weekly turn, trimming close along fences and foundations, hauling the clippings out before the evening damp settles. Greenburgh's lawns are small-scale and much looked at, tucked between hedges and driveways, and they show every shortcut, so none get taken. Come autumn the same routes turn to leaves, pushed down out of the maples in one long sweep toward the curb. It is ordinary work, done in order, and the whole street reads better for it.
