To the O.P., thanks for the head's up. These are the "data points" that one has to consider in Mexico. I'm constantly amazed at the disdain some display for warnings such as these. Naivete comes to mind. To put the risk of violence in Mexico in the same category as something that "could happen on 405" in Southern California, as a previous poster has done, is asinine. For the record, I've traveled Mexico since 1968. The O.P.'s post reinforces the need for the extra awareness, caution, reliance on instincts and common sense that has always been a rule of thumb in Mexico. This is especially true in today's environment.
