Sugar Grove sits on some of the blackest soil in Illinois, and the grass knows it — by the middle of May a yard out here will put on half an inch overnight if you let it. Blue Hills, Inc. keeps lawns around the village on a rhythm that matches the ground: cut before it gets ahead of itself, trimmed along the fence posts, edged where turf meets driveway so the line reads sharp from the road. Mornings start early, when the section-line roads are still cool and the corn past the last subdivision is only knee-high. There is something plainly good about the final pass of a day — even bands laid straight, clippings swept off the concrete, a yard that looks attended to. Autumn drops its leaves all at once in this part of Kane County, and those get hauled away too.
