Will London be as British as Vancouver is Canadian?
It is hard to convey just how Canadian these have been.
Multi-Olympic veterans to whom I've spoken are in awe of it. Even Canadians seem occasionally taken aback. Vancouver is a city painted red and white, partying long and loud into every night on the crest of a wave of national fervour. Each gold medal is a new excuse for Canada to celebrate the fact of its existence.
I have sat and watched as floods of fans transformed empty venues into a seething mass of maple leaves - nowhere more so than the Olympic ice hockey arena, , for on Thursday.
Enclosed arenas amplify noise at the best of times, and the crescendo as the Canadian team took to the ice must have made the home team feel 100ft tall. It is hard to recall one fan who did not turn up in national colours.
That has been replicated at every venue, in every event, and out on the streets no matter the day of the week. Is that simply what happens to Olympic host cities, or has this been a peculiarly Canadian phenomenon? Will London 2012 feel like this?
