We drove through Mexico in our own vehicle. A mexican tourism guide gave us a good route to follow (including but not limited to): Puerto Vallarta, Guadajara, Leon, Pueblo City, Oaxaco, San Cristol de las Carcas. We are now heading back to the US border and would like to know where not to go due to safety. We know that Chihualua is not a safe place. Are there other places that we should not go?
