Re: Susquehanna River Boating
You have to launch below the Coniwigo Dam down near Havre de Grace, MD to hit the Chessie from the Susky.
But, since you are coming from Scranton and are considering a long ride to the Chessie, you should launch somewhere into the Delaware River and head south the the C+D Canal (sea level; no locks), which connects the Delaware River to the Upper Chessie.
That, my friend is the move to make. Take the NE extension south til you can launch in the Delaware River somewhere.
