All wonderfully superglued tight to the GRINGOLANIA scene with the exception of Merida, Queretero and SCdLC. I try to avoid places that have downtown area business signs like SHUT UP FRANK'S, JOE'S RIBS, and SURF AND TURF, regardless of their apparent safety rating.
"Staying Safe" could be defined best as starting off on the right food and spending the least amount of time as necessary in problem areas, and diverting if not truly inconvenient around areas that simply have too many problems for comfort.
Parking in a dark area of an RV park in the middle of a city that has a hole in the RV park fence is not smart. Overnight stays in a pitch black area of a gasolinera isn't safe as well. Nor is walking home at 0200, getting roaring drunk in a pool hall, or any of ten thousand other acts that have been tried and decried on the net having been met up with nefarious predators.
But making a "list" of SAFE AREAS to me is an act of desperation or ignorance. HOW TO STAY SAFE, is far more important. If you ask me where to find such a piece of advice, try THE PEOPLE'S GUIDE to MEXICO.
A sample of a private conversation I had a few years ago. it is VERBATIM...
"What! I cannot wear my Rolex in Mazatlan? You have got to be kidding me!"
"And my 20 dollar gold piece belt buckle. I am NOT going to part with that! It is my lucky piece! I never go without it"
"And now you're telling me I shouldn't go around with my wallet full of credit cards! A phony wallet" Are you from the far side of the moon?"
