It's not clear to me that the indicated grass area is actually public.  According to Johnson County property records, the land used by the trail is public (owned by the city of Overland Park), but the land immediately to the west and north of Melrose is private property.  These private properties connect at a common point at the end of Melrose, meaning that passage from Melrose to the trail, although physically possible, most likely requires one to cut across private property.  For that reason, I don't think it's advisable for OSM to add this connection, unless there are other indications of its legitimacy.  Is there any signage that directs people to use this shortcut?
