The fact is nobody knows how many people will wander into the city on any given day just to have a look round. Nobody knows how many Sydneysiders who would normally be in the city will instead stay away. Nobody knows what the weather will be like or how hard it will be to get a cab. That is, of course, what makes it all so exciting. Nothing like this has ever happened before.
Nobody can say how it's going to go.
Nobody knows a damn thing really. But I will tell you this. It's going to be great.
