I have figured out logistics on where to stay for the route that is shown in the link at the end. Start in Republic for one night. Go to Colville for one night. Then on to Metaline for the 3rd night. Only 100 miles broken up with stops of views and history. Tell me what you think...is there interest? Dates would be Columbus Day weekend or Thanksgiving Day (October) for our Canadian friends.
Here is the map link:
I like this route. We'd go up to the border and follow the Columbia back down to Kettle Falls, then continue meandering back home afterwards.
