Hey Norm, good to see you are still around!
The trip sounds fun and a very good excuse for the long time no see. Someday...
Anyway, I don't have any recommendations down your way, my standard recommendation is usually Smart Service (a very good independent shop where all 3 techs know the SVX very well), but they are located about 20 minutes north of Seattle.
Of course, if you were to come to the Fall Colors Tour Oct. 16th....
Let's see, you could make an appointment to drop it off with Smart Service Friday morning, they'd give you the free rental car (for that kind of service), then pick it up Friday night, drive up to Earl's for a BBQ (sorry, our Bulgarian member is currently in FL), spend the night there, and be ready for the meet on Saturday!
