A cyclist makes his way across the Harbour Bridge during a protest in Sydney's rush-hour traffic to illustrate the benefits of public transport and bicycles over cars November 27. About 1,000 cycling campaigners, calling themselves Critical Mass, were joined by skateboarders and rollerbladers in the rally which severely disrupted Australia's most populous city in an effort to reduce the number of cars on the city's roads.
