It is so glad to know there are others with the same dilemma... I will look into the info you have given me and would also like to give you some info. In my research, I have come along a book that gives directions for navigating the rivers, by Zadok Cramer called The Navigator. Here is the website I found it at. Very interesting! Maybe too early for your research, but interesting read nonetheless. I have a person in Cincinnati looking into passenger listings for me. I'll let you know any findings I have.
