Used to hit the Susquehanna in canoes every other year with a bunch of guys from up an down the east coast. Camped at the confluence of Suskie and Juniata, seems like it was just under a tunnel NW of Duncannon. We'd float up and down between there and a pullout just downstream of the little Statue of Liberty This was before the smallmouth population started getting the lesions or growths or whatever. man, they were like footballs then!
Found out a lot about PA boating & fishing laws also, license visible on back of shirt or front of hat, and that even with only a trolling motor on a canoe, you needed State numbers and can get a PUI (paddling under the influence). Yes, there were a few guys that found out by getting some healthy fines!
