Subcommander Marcos and a band of Zapatista rebels have embarked on a 2,000 mile journey to Mexico City as a way to raise the profile of their cause and put pressure on the government of Vicente Fox to address the grievances of indigenous Mexicans, especially those in the southern state of Chiapas. The road tour is being conducted like a carnival, but counter-demonstrations have been promised by opponents along the way. Thirty-three public events have been planned on the 16-day trip. If you happen upon one or plan to attend, consider keeping to the margins in case opponents start trouble.
