David,
I knew I had seen the dates differently some where.
here is a site to a revised list of dates:

It seems that Twain's schedule was:
Aug. 7 Spokane, Wash.
Aug. 9 Portland, Ore.
Aug. 10 Olympia, Wash.
Aug. 12 Tacoma, Wash.
Aug. 13 Seattle, Wash.
Aug. 14 New Whatcom, Wash.
Aug. 15 Vancouver, B.C.
Do I have it right now?
