text: In Bogota, Colombia millions of Colombians hiked, biked, skated or took buses to work during a car-free day. Leaving the streets of this capital city mistirious devoid of traffic jams. That was the three years in a row that cars have been banned with only buses and taxis permitted for the day without cars in this capital city of 7 million. The goal was to promote alternative transportation and reduce smog. The people that ignored that faced a $25 fine.
