text: In Bogota, Columbia, there is a day set to be car-free, which allows millions to use sources of transportation other than cars. "Millions of  Columbians hiked, biked, skated or took buses to work during a car-free day yesterday," (Selsky, 20). By walking, biking, or using public transpotation citizens around the world and even in America, can get around using a car. When driving to work, you can encounter traffic jams, or wrecks, but by using a bike or by walking, you can bypass the stress. "When I had a car I was always tense. I'm much happier this way," (Rosenthal, 3).
