October along US-23 below Alpena has a color all its own: jack pine gone dark, hardwoods turning, the lake grey and loud beyond the trees. Kollien Property Services spends those weeks on the last cuts of the year and on the cleanups that matter most up here, clearing leaves and needles off the turf before snow presses them flat until April. Through the summer the same yards are mowed on schedule and trimmed close to the limestone outcrops and the stumps left over from clearing. The soil is thin and sandy, so a lawn in Sanborn is something you keep rather than something you assume. By November the grass lies short and clean and ready to sleep.
