Every Sunday, the streets of Bogotá, Colombia, are emptied of almost 2 million vehicles and motorbikes to make room for cyclists, roller skaters, scooter riders, and skateboarders.The 1.5 million Bogotanos who take time out of their week to enjoy the festivities each Saturday night consider the event, which began as an ecological experiment, to be a precious gift.Ciclovia, which means “Bicycle Way,” is a global phenomenon that has already taken hold in cities throughout Europe, China, and New Zealand.Another option is to get some of the world’s greatest street food and kick back.One of the things Sarmiento appreciates about the program is how it brings people together and eases tension in Colombia, a nation ripped apart by war and deeply divided along class lines."
