Up toward the Wisconsin line the ground stops being flat. Rock City sits among low hills and dairy pasture, and on a Saturday morning the dew doesn't leave the north slopes until well after breakfast. Mashaw's Home & Lawn maintenance works the village lots and the places just outside them — mowing, trimming, cutting a line along drives and walks, clearing beds, and hauling leaves off in fall. Sloped yards ask more than level ones; the cut has to be read hill by hill. What comes back is a lawn that lies even from the road to the back fence, in a corner of Stephenson County that has always kept things neat.
