Northern Oregon

There are some really great roads in northern Oregon.   When you cross into Astoria take Saddle Mountain Road, Foss Road, Miami Foley Road...down to Tillamook.  Miles and miles of twisty roads that you can take at a leisurely pace.  I don't recall the scenery being great until you get to the coast, but if you want to practice your twisties these are good roads that just go on for miles.
