Up in Ogemaw County the jack pine gives way to fields and closes back in again, and the Rifle River country keeps its mornings cool well into summer. D. NICHOLS LAWN CARE SERVICE, LLC. mows across that township — yards carved out of the pines, open frontages along the county roads, everything cut, trimmed and tidied before the truck moves on. The season is short here and every good week counts, so the routes run tight from May to October. A mowed yard set against all that northern woods is a small, satisfying piece of order.
