text: The City of Bogota, Colombia has started a car-free day. And apparently it's a big hit. Its goal is to promote alternate transportation, and reduce smog, with the exception of buses and taxis. That day, millions of Colombians either walked, hiked, biked, or skated. And even though there was some gray clouds with a bit of rain, it didn't stop many people. It is also seen as an opportunity to help lower stress and air pollution. And to show its popularity, two other cities in the county; Cali and Velledupar have joined in on the event. Even the mayor of Asuncion, Paraguay came to the county to say how great of an idea it was. More parks, sports centers have been buit, and 118 miles of bike paths have been created. On top of that, new side-walks have been built to help people in general.
