To make the event even bigger and better, there are a few things any participant can do to help. If the event is to keep going, people need to get involved. This can be as simple as telling your friends, or as exciting as getting on TV.

Beforehand: make placards from cardboard and bits of scrap wood, paint old sheets as banners; use them to tell passers by why the mass is happening. Things like statistics about road deaths, air pollution, the car industry are good. They can be found on environmental campaigning groups websites for example. Court the media, especially if you have any friends who work in the media. Get them interested, get the issues about cars and roads and transport systems out into people's sitting rooms, and get people onto bikes, and along to critical masses..

You can also make up leaflets to either publicise the event before hand, or to hand out on the day to people we pass by and interest.  There are copies of the ones already being used in Cardiff here. Or you can make your own. It is an idea to ask for donations from people at the demo to put towards printing.  Add the event to listings magazines if it is not already listed, write letters to papers etc. The more people we get along, the better it is…

On the day: wear costumes, decorate your bike, carry balloons, paint your face etc.   Bring whistles, horns, bicycle bells, instruments, make up songs and slogans to sing and shout to passers by, like oil spills, oil kills.  The more noise we make, the bigger our presence in the street, the more people see there is an alternative to boring, destructive, dangerous car culture. It also makes it more fun to be involved in, and it is supposed to be a carnival after all.

Blocking the traffic? We ARE the traffic.
