There is a week in November when the cottonwoods at North Lake Park finish dropping all at once and the first serious cold slides across the plain, and that is when the work changes hands from mower to plow. Heaberlin Lawn Care Co. carries Loveland properties over that line — mowing, trimming and cleanups through the warm months, then plowing drives and clearing walks once winter takes the town. Knowing a yard in July helps in January: where the drive pitches, where drifts pile against a garage, where the ice likes to sit. Both jobs come down to the same thing, which is a place looking cared for when somebody pulls in. Spring returns, the snow goes off the north side last, and the mowers come back out.
