I picked up a copy of United Airlines inflight magazine (July issue) and there was a reference to the "Spokane Loop", but it really didn't give many details. All that was written was a paragraph.
The description of the route had the traveler flying in and out of Spokane. The loop was listed as 845 miles. The little article had a very simple line drawing, showing no cities other than Spokane and Calgary. The route appeared to go a bit northeast, up into Canada, then take a little side trip, on up into an area with mountains (shown on this very simple line drawing), head east to Calgary, then circle around back into the US and back to Spokane.
Does anyone know the specifics of this route? It looks like an interesting drive - if I only knew more of the specifics.
