This is footage of the inaugural Surrey Critical Mass. The ride even got the support of transportation minister Kevin Falcon, chief promoter of the Gateway Project. Surrey is very much a city built around the car, which might explain why there was such a warm response to the unusual sight of 50 plus noisy cyclists riding through the rain. However, there was an incident, involving a dump truck and several cars in a very big hurry.
