text: Bogota in colombia has set up a program to where once a year they have a day where no one in the town uses there cars. It is hard to belive that 7 million people would do it but its very true. Even with those who have to drive there car they get taxed a $25 fine. doing this international day has lead more and more citys to stop using ther cars as much and just walking because it relives traffic jams and other stressful things.
