Lyndon Township is glacier country — hills folded up like a rumpled quilt, kettle lakes set down between them, and gravel roads that climb and drop before they ever get around to going straight. Ghost Window Cleaning keeps lawns here in order, mowing the long slopes above the water and cutting a clean line where turf gives way to gravel. Summer mornings come up out of the Waterloo woods with mist still lying on Sugarloaf and North Lake, and by nine the grass is dry enough to stripe. Autumn is leaves — oak and hickory by the bushel, raked off the beds and hauled away before the first hard frost pins them down. There is real satisfaction in standing at the end of a drive and looking back at a yard that finally looks tended.
