The I-5 Corridor of Oregon and Washington (a.k.a. The Wet Side) have worked out well for me since 1989.
Never gets too hot. Sure it rains some the roads are generally clear of snow and ice about 360 days a year.
The great roads are alomost endless. (Dirt and Paved)
CA. is a nice place to visit or ride through but I would NEVER live there.
