Greetings from the Great American Desert (snow ... snow ... snow all day long):
One of the long distance routes I'm considering would go northwest from Blackfoot, ID - via state highway 26 - and then pretty much due north from Arco, ID to Polson, MT - via Missoula - on US 93.
Even for the Fountain of All Knowledge (the Internet) touring information on this route is very hard to find. (The Adventure Cycling routes go substantially to the east).
Any thoughts on riding through this area?
