There is a particular pleasure in a long straight line held across an acre of open ground. Green Lines Lawn Care & Tractor Works LLC brings tractor and mower to the roomier properties of Kalkaska township, the field edges, the drives that run a quarter mile back, the yards that stop being yards halfway to the woods. Late spring is the busy stretch, when the grass comes on all at once and the shoulders green up along the county roads. Mowing, trimming and seasonal cleanup are the work; the striped ground left behind is the part people photograph. When a big open property is kept sharp, the whole road it sits on feels different.
