Some team going to the wrong Portland would be an unprecendented mistake for sure! Still, there have been two teams that finished third but weren't able to get to the Finish Line in time: Team Guido (thanks to falling so far behind in Asia), and Dave & Jeff (who took a risky flight -- I think it was to Sydney -- and couldn't get to Hawaii until the others were already on their way to Arizona, at least). In any case, going to the wrong Portland and finding out while they're on their way there is as good an "unprecedented mistake" as any.
