These tracks once hosted the Eastern RR from Boston to Portsmouth. Today this is a way to cross the Hampton Marsh on foot, away from the traffic of Rte 1.
We took GPS readings beneath the high-tension wires of the Seabrook Nuclear Power Plant. Because any GPSr can be jumpy in these conditions, we added a photo to give you a visual to the area in which our cache (a bison tube) is located.
Enjoy your stroll!
