I think it's typically in August for summer Olympics (unless it's in Austrailia of course).
I've never been huge on summer Olympics, I'm excited for 2010 in Vancouver. The last winter Olympics I hated having to go to class because I wanted to stay home and watch. I'm going to Vancouver in 2010 to go to some events.
A.B.: It's not anti-climatic if you don't check the results before you watch the days events. I ONLY get Olympic info from CBC on TV, that way I see the events without knowing the outcome.
