Mexico is getting rougher and rougher, and news broke today that three major states are on the "do not go" to list so to speak. It's a hard thing to really understand, but maybe it will deter some more brave souls from going to get drunk in the Mexico resorts.
I would like to visit Argentina, personally.
Some of the highlighted states are home to popular tourist areas, including forest-covered mountains in Michoacan where Monarch butterflies winter. The department said U.S. citizens "should exercise extreme caution when traveling in Michoacan, especially outside major tourist areas."
The statement also cited "recent incidents of serious narcotics-related violence in the vicinity of the Copper Canyon in Chihuahua," another popular tourist spot, and warned that areas of southern Guerrero state — where the resort of Acapulco is located — could also be dangerous.
