Have they ever fixed up the trail around Lake Scranton? That's one of the prettiest runs around although I'm not sure I'd want to do 4 or 5 laps to get 15 mi.
The Forest City trail would be great but they re tearing up right now to install that fracing pipeline.
The Susquehanna Warrior Trail is nice for a long run if you want to drive to West Nanticoke.

Of course, the Lehigh Gorge trail is great but it's an ever farther drive.
