Its a hard question in terms of sporting moments or opening ceremonies?
For me without a doubt hands down its London 2012 in terms of organisation, multiculturism and public support.
for me it is london 2012 because I am english and it is the first Olympics I have ever seen but from now on I am going to watch it every time
Beijing 2008, without a doubt. That truly was a spectacle.
Summer:
Athens
favourite moment- bjork's performance
Winter:
Vancouver (they're the only ones i can remember and they were in my country, so they win by a default)
favourite moment- the parade of nations
What's your vote guys?
