Zacatecas is a Mexican federal state located in north-central Mexico. It borders the states of Durango to the northwest, Coahuila to the north, San Luis Potosí and Nuevo León to the east, Aguascalientes, Guanajuato, and Jalisco to the south, and Nayarit to the west. Its capital is the city of Zacatecas. Another important city is Fresnillo, located north of the city of Zacatecas on the main route to the states and cities of Durango and Chihuahua. Going via Saltillo to Monterrey, it is currently recommended going via San Luis Potosí, as rumours (i.e. people on the toll stations) say it might not be safe going through the sparsely populated northeastern part of the state (Zacatecas is not known for being especially unsafe though). Anyway, ask around when you are there, things might have changed by now.
