From the footbridge at Portland the Delaware runs green in July and steel-colored in February, and the work changes right along with it. JRB landscaping and snowplowing mows, trims and edges through the warm half of the year in Upper Mount Bethel township, shaping beds and carting off whatever the season sheds. The cold half is plowing: driveways and lots opened up, walkways cleared, salt worked into the spots that glaze first. Night runs are the trade — headlights, a blade, and a driveway that looks untouched by morning except for being clear. Both halves come down to one thing, a property somebody can actually use.
