Because I am the foolish sort, I'm riding my Kawasaki KE100 from Chicago to Bow, WA where my wife will be working on a tree farm. It's not the fastest of bikes, but it's fun. Current plan is to mostly use US-2. I also have an affinity to ride roads where "Old" has been added to its designation.
Without knowing much about the area, here's The Route through N Idaho
I'll be coming from the Glacier National area and think I'll take WA-20 after. Open to suggestions.
The main trip planning thread is here KE100 - Slow ride Chicago to Pacific Northwest
