I Just addressed this in changeset #154907655. I was just here and it appears that the patriot's path markings are sparse but only on the east side of Ironia Mendham Road up until North/Dover-Chester Rd. After that intersection, there were markings on the west half of the road. Just fixed this trail to follow the markings.

The section that goes into the woods on Hugg Rd was very slightly off so I made the entrance a bit closer to dover-chester/north rd than walnut st. The trail entrance is a bit overgrown but they've put in a big post to indicate where it starts.

Also, there is no sidewalk or marked crossings, so I guess people are expected to walk on the road for this section.
