We wanted to avoid the ho-hum drive on I90 through Washington which we've done many times. We'd never taken the 2 across Washington and I have to say, if you aren't in a huge hurry it's great.
Here you can see photos from the nearly defunct town of Douglas, Washington as well as our little jaunt around Leavenworth (which I had never been to either). The rest of the photos are simply open stretches of road, abandoned structures, and a wheat field. It was a nice change of pace from I-90.
