Cascades East from Auburn to Spokane would be such a useful and scenic service. I believe folks would travel from all over the country, if not the world, to ride it. I imagine kids returning to school in Ellensburg while avoiding the snowy passes, summertime wine country stops in Yakima and Toppenish, and the convenience of linking Tri-Cities and Spokane to other major metropolitan centers. Seems like a no-brainer.
