On the last Friday of September, 1992, a group of San Franciscan cyclists showed up on Market Street for the first ever Critical Mass. This leaderless ride became a monthly “organized coincidence”, and in the years that followed, spread around the world. Celebrating a shared sense of rediscovering urban spaces, Critical Mass riders cross borders and find common cause to have a good time on foot-powered wheels. These uplifting rides also challenge the use of city streets and the domination of cars and oil in our transportation system.

• DIT (Doing It Together)
Critical Mass is an open idea. There are no leaders or members. Volunteers are appreciated. This is by no means a closed schedule for enjoying the 20th Anniversary. All celebrants are encouraged to create their own happenings in addition to the above activities, especially if it makes everything more fun! And let us know so we can help promote it along with the already-scheduled events.
