I have been interested in the Susquehanna also. I will not say I am familiar with the river, however, I also live in upstate NY and whenever I drive south through PA alongside the Susquehanna I wonder about boating on it. Most of the river I have seen looks wide and shallow, lots of rocks visible in places and I have wondered about the absence of boats on the river. I cannot remember seeing any waterfront developments in the river towns I have been through. But again this impression is what I gathered from the road and I might be completely off base. Last year my wife and I drove north on PA state route 11 which goes along the river in the area south of Wilkes-Barre. I would suggest getting a map and checking the name of towns and cities along the river such as Moncanaqua, Lime Ridge, Bloomsburg, etc. and then checking the internet to see if any have a web site which might mention recreation, boating, fishing, marinas, or boating related activities. I would be interested to see what your research comes up with, good luck!
