We are also in the planning stage. Have a wedding in Portland next Memorial Day weekend and thought we would use the excuse to do our bucket list of seeing the country we love.
I'm using the Rand McNally/Good Sam route planning software for the initial plan and will order the Mountain Guide to refine it. We have a 36' Safari Cheetah Diesel with a toad. Starting point is south Florida.
I'm not certain how much time to plan for so I'm using two months as a starting point.
I would appreciate any suggestions and recommendations for interesting things to include on our itinerary. We love browsing old "high class junk-low class antique" type stores.
I do know that Yellowstone and the Grand Canyon are must stops on my personal list (Since I've been 13 I've dreamt of seeing sunrise at the Canyon while listening to Ferde Grofe's Grand Canyon suite
) We are also planning on visiting the wineries on the coast going south from Portland.
