A: On Yer Bike!
Q:How can we move around our crowded and polluted cities?
This, is Critical Mass. On the last Friday of each month for the last 12 years, London cyclists mass together for a random ride with a simple message - "We are traffic too". It goes on around the world, there is probably a ride near you. The ride is good natured and the police generally take a very constructive attitude. Last October, they handed out leaflets saying that the ride was illegal, so a Court case has been brought which is in the News at the moment.
This picture is what happens when 300 cyclists ride around Parliament Square - look - no cars!
