This is one of the funnest commutes I have ever gotten to do.
I lived in Hillsboro, and was working in Newberg and Hwy 219 goes directly between the two. It is 20 miles long, and about half of that is very twisty and curvy. Takes 30 minutes regardless of the time of day (unless there is an accident).
I didn't have a WRX at the time (still don't, but I will in June) but it was still a fun commute twice a day.
