So I stood on Collins Street.
At lunchtime, during the Grand Prix parade.
And I saw lots of barricades.
And I saw crowds of people.
And they were watching an empty street. Some were even taking photos of the empty street. (It would seem the proliferation of digital photography has resulted in a lot more taking of pointless photos.)
I stood with them for five minutes. And the only moving vehicle I saw was a hotted up car doing laps. Nothing more than you might see any revhead driving any day of the week.
Then I got bored and went back to work.
