I grew up in Banks and have been everywhere almost, between Seaside and Portland. Brought back many memories watching this trip. The Oregon coast highways have some of the most amazing views. Been across the country and back and moved to Arizona from Oregon at the beginning of the year.
I agree, after seeing more of it I think it has more to do than Washington state. It helps that there are less people there and still lots of natural areas left.
Oregon is a very interesting state. I'm from Florida but lived there for several years for college. I remember driving from PDX to California and also from PDX to Idaho
I lived in Hillsboro some years back. Have you done the TV Highway drive between Portland and Tillamook ? I am surprised those big stands of Douglas fir are still there.
