I would like to make it from Los Angeles to coastal Oregon and back in 8 days. Hopefully this is possible. Since I've never taken this route before, I'm hesitant to book any motel rooms along the way because I don't know what I will see, or how long I will want to stay. I would rather face sleeping in my car than hotel cancellation fees. I will be leaving the day after xmas and want to know if the rain will ruin the trip. Will there be enough to do, even if it rains the whole time?
