I've been planning a trip to Spokane for this summer. My thoughts would be to fly to Spokane, drive to Couer d Alene (overnight) drive though I Idaho down to Walla Walla (overnight) and back to Spokane (overnight) Has anyone done this? I'm not sure how long I would spend in each city, but I hope to take in scenery, farmer's markets and of course a couple wineries. Any advise on how long these drives take? Any other information is much appreciated.
