There is NO ACCESSING THIS CACHE FROM EITHER I-95 OR THE SPAULDING TURNPIKE. Instead, it's a short hike or very short bike ride from the provided parking coordinates. You SHOULD also be able to park at the trailhead coordinates off Rockingham Avenue. There is room to pull off and I did not see any No Parking signs. Terrain rating is based on walking distance from the posted parking coords.
A nice little ped/bike trail if you want some sunshine and don't mind the noise. There are a handful of caches out here to make it a worthwhile side trip. Plus you're treated to some differing perspectives of an area familiar to most of us locals. Enjoy!
