I rode this section at the tail end of a cross country a few years ago. Perhaps I was just tired but the Oregon side confused the hell out of me in a couple of places. I was surprised by the lack of signage for westbound cyclists, especially directions for the historic section. Someone already commented on it but the noise was a major issue for me after a couple months in wide opens spaces. Were I to ride it again, ear plugs would be a part of the plan! Don't miss the awesome little park at Roosevelt-it doesn't show up on some of the maps. Looks like the new trail Medic talks about might help a lot.
