text: In source 3 by Andrew Selsky: Car- free day is spinning into a big hit in Bogota, is important because there is a program that is set to spread to other countries around the world, millions of Colombians hiked, biked, skated or even take buses to work during an car free day. For exmaple, in paragraph 21 said " It was the third straight year cars have been banned with only buses and taxis permitted for the Day Without Cars in this capital city of 7 million" what this mean is that during the third straight years cars are banned and only buses are allowed this can promote alternative transportation and will reduce smog in the long run.
