It's actually quite funny walking along chatting to someone and having to dodge dozens of people taking pictures of Parliament, buses, traffic lights, taxis, the River, the Eye and so on. It requires a sort of crowd mastery to stay close and able to talk in a tourist mayhem.
To make it even more challenging, there's one of those gangs of tourist fleecers operating on Westminster Bridge at the moment, complete with home made plastic disks and metal cups for the three shell game.
Its always interesting to watch the edges of such games. There'll be someone standing in the road looking for police. There'll be a couple of extra large people around for 'management purposes' and the actual crowds around the makeshift tables seem to comprise quite a few people of similar ethnicity as the people operating the games. The marks seem to frequently be from the far east.
A couple of days ago a single policeman on a motorcycle arrived and in seconds half the bridge's hustlers had disappeared.
But I don't think of this offshore short-con as a London thing. I've seen it in Paris and Milan, but in truth am a little appalled we have it operating across the road from Parliament.
