We snagged some of the yellow booklets explaining the whys and hows of the program to encourage bike use. The material presents some compelling reasons for mejor en bici ("better by bike"), the slogan for the program. Most trips made in Buenos Aires are under 5 km, a distance easily covered by bike. Benefits include better traffic circulation, personal health, and the environment, not to mention the cost savings associated with NOT using a car.
We were caught without a camera, but there are lots of good photos plus more information on Facebook.
