I haven't really set a date for this yet, but I suspect it would be in September or October. I did this trip last year, and the road from Redding to Yachats, OR was amazing to drive.
Since I'd also be looping from Seattle down to California and back, this is also sort of for those in the Pacific Northwest as well, but if anyone down there in California wanted to join for the Saturday leg, you're welcome to. I'll have more details soon when I set a date.
Here's the thread if you're interested:
