text: Some cities have days that are completely car free. Bogota, Colombia is one of them. They have been having a Day Without Cars for three straight years. Cars are banned for the day and buses and taxis are the only exception. The city holds about 7 milion people, and had a large turnout. "It's a good opportunity to take away stress and lower air pollution," said businessman Carlos Arturo Plaza. The mayor of Asuncion, Paraguay even said that, "These people are generating a revolutionary change, and this is crossing borders." The Day Without Cars has even helped stores and sports center come up throughout the city. Instead of shopping centers along a highway, those stores are now in the city and easy to get to without having to use a car.
