The U.S. Consulate is issuing a warning to those thinking of traveling to Mexico during the upcoming holidays. The alert urges Americans to travel smart, avoiding pitfalls that could lead to an arrest. That includes following local laws regarding drug possession and use, firearms and imported goods. Drivers are encouraged to cooperate at all road checkpoints to reduce the chance of violence. The consulate also urged caution at popular winter break spots such as Mazatlan and Los Cabos, especially after dark.
