This is a good list. One place I would go back to (and do often) is the Oregon coast. Summer temps in the 60s, they consider it murderously hot if the temp ever touches 80. Rugged beauty. The people are nice.
I highly recommend the Shakespeare Festival in Ashland. A world class event. Feb-Ict every year. Multi-le plays and different venues. Then Oregon Caves and jet boat out of Medford. Before or after the coast to kick back and relax.
