[700rpm]

I have to disagree with my friend Pluck. The Oregon side is all freeway (I-84) until 20 miles west of Cascade locks. It is heavy truck traffic and a hair-raising drive in a Model A (voice of experience). You can exit onto the the old highway at that 20-mile spot, and it is much nicer from there to the Interstate Bridge. But that's where you meet I-5. You can get off I-5 fairly quickly once you cross the Columbia, but it takes some careful planning to get to Puyallup from Vancouver on surface streets. Hwy 14 is much more Model A friendly. I have driven it many times and there is adequate room to pull over, but from Umatilla west to about Bingen there is a paucity of gas stations. Still some truck traffic, but not near like I-84.
