The worldwide web-wheel of the organized coincidence known as Critical Mass. Critical Mass is a monthly event occuring in hundereds of cities worldwide. Cyclists ride in a group through the city streets to celebrate cycling, fossil-fuel-free transportation, redefining of the social space of our cities and reclaim autonomy in an automobile dominated society. It's loads of fun too. The revolution is riding a bike!

When man invented the bicycle he reached the peak of his attainments. Here was a machine of precision and balance for the convenience of man. And (unlike subsequent inventions for man's convenience) the more he used it, the fitter his body became.

The first ride consisted of 3 people... who didn't ride. Instead, they began planning bigger and better things - to take the buckle-of-the-bible-belt by storm... to shock 'em awake... it's here, whether /they/ like it or not...
