The Olympics are in full swing (I understand), and the effect on London has been very strange. Most of the city, away from the obvious Olympic 'hotspots', is eerily quiet - quieter than I've ever known it in recent years. It seems the first impact of this Olympiad has been to drive people away from our capital city and spark a mini-recession in the one part of the country that makes any money. Shops, theatres, museums and tourist attractions stand empty, tumbleweed bowls down a deserted Regent Street, coyotes howl in the distance... Personally of course I blame myself. The persistent warnings of gridlock, chaos, riots, famine and pestilence on Nigeness - the blog the world reads - have had their effect. Sorry about that - but it does make things surprisingly agreeable for those of us obliged to carry on commuting in Olympic London.
