Oak Park keeps its parks close, so a ball diamond or a stretch of open green is never far from a front porch, and the yards around them get held to that same standard. S & B Landscaping mows, trims and edges through the growing months, then clears drives and walks and lays salt once the field goes hard and white. The pleasure of the job is contrast: the shorn stripe against the shaggy, black pavement against a wall of drift. Both come from the same instinct, which is to make a place usable again. The ground stays in service either way.
