It should be a beautiful and fun trip and yes, I hope you have the wind at your back in the Columbia River gorge too! I've done most of the legs on this route and think you'll really enjoy it. Walla Walla, WA is wine country, and so is the lovely Willamette river valley, OR - so maybe you'll have some great winery stops? I did a hot, hot, and hard century into and out of Hells Canyon a few years ago and have also gone on the Tour de Tetons with Womantours, that was very fun and well-supported.
Fyi, it's been hot and sunny - even in Seattle lately - and we're expecting temps in the 90's this week, so pack (and ride) accordingly.
Have a great trip!
Mary
