StumbleUpon led us to discover the Car-Free Day Wikipedia entry. Every September 22, Car-Free Day inspires drivers to use alternative modes of transportation – like cycling and walking – with the hopes of developing communities where jobs are closer to home, and shopping centers within walking distance.
This strategy and plan for reducing car dependence in cities was first proposed in 1994, and challenged a city, neighborhood or group to spend one carefully prepared day without cars and observe closely what exactly goes on throughout the day. Events are organized globally and vary by location, yet the goal is to encourage commuters to experience their locality from a different perspective.
Bogotá, Colombia has held the worlds largest Car-Free day event spanning the entire city since February 2000.
