For the record, I've been to Mexico well over one hundred times, conduct business there and have been ALL OVER the country, from the most remote places in Morelia, Oaxaca, the mountains near Durango, the hydro dam near Tepic, Veracruz, Aguascalientes, the old Colonial cities and towns, the jungles and mountains, the border cities and states, all over Mexico City and Guadalajara. You name it.
In 1975, we did a twelve thousand mile trip around Mexico and Guatemala in a VW bug, was robbed at gunpoint by banditos in Zacatecas, and by Federales near Z-wat. BTW, the banditos treated us better than the Federales. That was another time then, and if now, we would have been killed by either!
Granted, one could get robbed or killed almost anywhere here in the U.S. The former, I know this all too well. And in Mexico, it's an unfortunate everyday nightmare for many!
The people are great there but you have an inordinate amount of corruption and drug murders happening all over the country.
Sometimes, full buses are stopped and people are ordered outside and are robbed, beaten and murdered... on a whim. You don't hear about this much on this side of the border.
When I deliver apparatus to Mexico, we NEVER park within sixty miles plus of the Laredo border! Absolutely never get close to it unless it's an in and out delivery. No more overnite parking within sixty miles of the border like we used to do!
Mexico has always been 'another world', a beautiful country with wonderful people.
Times have changed... big time.
BTW, if you haven't seen 'Treasure of the Sierra Madre', John Huston's magnificent film shot entirely in Mexico, see it! It's a gem!
Good luck on your travels in Mexico!
