FarWest - I am doing almost that exact ride between July 19th and 23rd with my father. I would say let's meet up if you were going to be doing it a weekend earlier. If you go earlier for some reason, PM me.
My plan is to ride down from Seattle to the Oregon Coast, stop at Florence, OR to ride the sand dunes on ATVs, do some camping, maybe go on a day long rafting trip on the Kalamath River or Rogue River, then ride through the Trinity Mtns starting at the coast at Eureka and do the Trinity Triangle between Eureka, Yrek, Weaverville, etc. I did this ride once before in 2005 and had a BLAST. I've only been riding a few years, but I have to believe this is some of the best motorcycle country around.
My original intent was to ride down to Laguna Seca for the US MotoGP; however, it's a little expensive attending the race, and I figured I'd have more fun spending an extra day or two riding back and forth over the mountains in Northern CA.
When I did the ride last time, I was on a Honda Shadow 1100. I'm looking forward to doing on my FJR this time.
If you're interested, I have a video of the ride posted on my Youtube account:
. It's about 11 minutes long and the CA portion of the trip doesn't start until about 4 mins in.
