Oh come on. Granted Oregon has more beauty while you drive down the road, ie trees and green shrubs and such, but California has way more miles of fantastic roads to drive on. However if you live in SF, you first have to drive at least 30 minutes to get a good road, but once you're there you can spend the whole day on them and never hit the same patch of asphalt twice.
That being said, I am an Oregonian, I love Oregon, I want to go back to Oregon, and my favorite road of all time, from Estecada to Detroit Lake, is in Oregon.
As you were.
