Got the Garmin GPS/Depth Finder with my Thunderjet, but I never did get to getting the downloadable chart maps, anyone recommend a good source for areas along the coast and of course becoming my favorite river the "Columbia"? Didn't think I would neeed them, but boy was I wrong, man good charts make a huge difference ibottom structure and other items.... Don't know if any of you are up grading to the 09 maps and want to sell the 06/07/08 versions or trade... Hoyt and Huntnphool what charts are you utilizing?
