Well, cartel activity is picking up everywhere. The bullshit going down in Sinaloa and other Mexican states is spreading like wildfire. Tourists are being kidnapped and used as leverage in drug disputes. True story.
The government is saying to avoid travel to Colima, Guerrero, Michoacán, Sinaloa, and Tamaulipas states. (Guerrero's capital is Acapulco).
In fact, many states on the Mexico travel list are at Threat Level 2-3 (exercise caution or avoid).
That list is here.
Just be safe, or perhaps get a passport and head down to Argentina/Brazil.
