Out at Plato Center the roads meet in a modest cross and the land lifts and settles in long glacial swells toward the Fox. TK's Lawncare LLC keeps the grass on those swells, mowing farm yards and village lots, edging the walks, and running the trimmer around posts, hydrants and the shade trees somebody's grandparents set in a straight line. Kane County summers can turn on a Thursday storm, so the schedule bends around wet ground and then catches back up. Late in the day, with the light coming in sideways across a fresh cut, the mow lines follow the roll of the ground instead of fighting it. That is the whole ambition here: a lawn that looks like it belongs to its own hill.
