Some mornings the Musconetcong lays a low ribbon of mist down the valley, and the lawns on both banks hold that damp until nearly nine. Diamond Edge Landscaping waits it out, then mows — clean passes across the open yards, a tidy collar cut around every post and mailbox, and an edge along the walk so sharp it looks drawn with a straightedge. Mulch goes down dark in April, leaves come up by the armload in November, and between them runs the weekly circuit of cutting and trimming that keeps a Hackettstown yard looking looked-after from the street. The name is a promise about a line, and the line is where the pride sits.
