Old Washington State highway maps

If by "BIA2" we're talking about the road that runs just about due north from the Keller Ferry to Republic, I can attest that it's just like 95% of the 2-lane roads in Eastern Washington: chip sealed,straight as a stick and punctuated with the occasional hamlet/dog sleeping on the center line.

And it's the only place EVER that I've actually seen a moose...took me a few seconds to register that the tall animal standing there completely indifferent to my approach was actually one of those critters that I'd only ever seen on TV before that moment...!
