By six in the evening the Kittatinny ridge west of town has gone blue, and what light is left crosses the valley sideways. Mission Site Management is often still out in it, working the long frontages and wide open lots that properties in this corner of Sussex County tend to run to — grass measured by the acre instead of the yard. Mowing sets the pattern, then trimming and edging bring the boundaries back in, and twice a year the cleanups strip everything down to a fresh start. Big ground shows every skipped detail from a hundred feet away, which is precisely why the details get done. When the last pass closes the field and the machines shut off, the quiet arrives all at once.
