Pretty straightforward, just yomp up from the Rookie Village to the Bus stop and the Mill, picking up anything that you may have stashed there in the interim. Move towards the embankment using the Mill buildings as cover and head for the location of the Journeyman on the minimap, avoiding any anomalies. Since the Journeyman is dead you may have to chase off a few Blind dogs before approaching his body. Searching his remains concludes the mission and provides the Traverse the Railroad Embankment mission.
