I don't understand why they'd want to do an international Olympics between Canada and the US. I mean, in theory it sounds cool, but with the multiple border crossings, the distance between each city, transportation etc. it just doesn't seem worth it. Are they going to put the Olympic Village in Mt. Vernon so it's almost equidistant to both cities (considering border crossing times)?
If there was going to be a joint bid for any cities in the PNW, it would be Portland/Seattle (Portland is only 30 miles further from Seattle than Vancouver, plus no border crossings) or Vancouver/Victoria. I just don't think an international Olympics would work because of the complications.
