I've enjoyed following this thread since I plan on a lengthy time in Mexico beginning in October.
Interesting enough, I had a conversation with a friend who holds dual citizenship in Mexico and The States. She has a very large family in MX and is very much afraid to go visit them, and because we are friends, is very concerned about my safety.
Her biggest concern is being caught in some sort of crossfire between the bad guys and the so called good guys. She believes Mexico's structure is so decayed that there is really no place "safe," especially if one is in need of help.
Different viewpoints from people of varying experience living or traveling in Mexico.
