YES!! But... I'm planning on the summer of 2012. I have a couple friends that I told I want to do this, and now they've taken over the planning and are planning a trip I don't want to be a part of. I shall have to try to find my own group to go with.
I would leave in late May/very early June and head east to west (because leaving that early in the summer I would encounter snow in the Cascades/Rockies). I need to leave then to be back home in time for school to start in early August (I teach).
Plus, I want the sun at my back each morning as I head out in the wee hours (and drivers wouldn't have the sun in their eyes coming up on me).
I hope you can find some companions to ride wtih. I'm so very excited to do it one of these days.
