As I replied, SSRT's trail map cannot be calibrated to be used in a GPS, but their trail map is pretty easy. It could be drawn in as a GPX file as its mainly the railbed plus 20 miles of twp roads.
I do have maps of Bloody Skillet, Whiskey Springs, Susquehannock State trails (though the trails are horribly inaccurate, but the intersections are good)
I do have tracks of the connector trail from SSRT to Bloody Skillet, but that trail is also well marked.
I use an Oregon 450t
