Got a Humminbird 581i with the GPS deal. I looked at the Navionics page, and what they seem to offer is a 1000 maps for a region that stretches clear to Maine and covers KY. Christmas! All I want is the Ohio River for 20 miles each way, Cumberland, Greene, Taylorsville, Nolin, Rough, and Barren

Does anybody know of any web site where you can go in and pay to just download single lakes or a more regional like by state set of lake maps. ?
