Calm before the storm?
When you consider the white knuckle ride some host cities have given the International Olympic Committee, it's no surprise that Wednesday's Downing Street media conference with International Olympic Committee president Jacques Rogge and British Prime Minister David Cameron was such a love-in.
At this point before the Athens Games in 2004, there was no roof on the main Olympic stadium in the Greek capital and hardly a ticket had been sold.
London's main venues have all been completed, have sold 4m tickets and have even secured legacy uses for six of the eight arenas on the Olympic Park.
But London's organising committee, Locog, knows there is still a lot of work to be done.

There are a further 4m tickets still to be sold, including, crucially, 1m tickets for the most sought-after events.
After all the grumbling about the ticketing process so far, Locog cannot afford any more slip-ups.
And while the permanent venues are finished, there is still the huge task of overlaying all the temporary venues, some of which are in some of London's busiest areas.
The beach volleyball stadium at Horse Guard's Parade, the equestrian venue at Greenwich Park, plus the road events and sports in Hyde Park, pose major challenges.
Then there is security. Cameron said he was happy with the plans because they would not be so overbearing that they would spoil the party atmosphere.
All that could change if there is a serious and credible threat against the Games. It is certainly the issue the IOC fears the most.
And while transport plans will be pored over in close detail by the final IOC co-ordination commission this week, there remain serious concerns about how London's transport network will cope, especially on the Friday of the opening ceremony and the first Monday of the Games when work commuters will be tussling with those trying to watch events.
In a slightly critical note, one IOC member told me last week he would like to see a bit more leadership from London on the transport issue.
He felt there was too much public criticism of the IOC over the notorious Olympic lanes and that the Locog leadership and the mayor of London should make a better case of explaining to Londoners why the lanes were coming and the broader benefits of the Games.
In London's defence, anyone who has ridden on the tube recently cannot have failed to spot the 'Get ready for the Games' campaign.
But this particular IOC member felt London could do a bit more.
Finally, the legacy problem continues to pose the biggest challenge.
Rogge said today: "I think it is time to tear up any notion of the Olympics leaving behind white elephants."
That might be a bit hasty given that the Olympic Stadium still has to nail down a long-term deal with West Ham, although this option looks likely.
And on participation legacy, the PM said, rather boldly, that the Olympics will "revitalise local sport in Britain for generations to come".
In a week of "pasty-gate" and questions over cash for access, could that be a comment Cameron comes to regret?
