Huatulco was a beautiful and safe place, many burnt out American kids found or lost themselves there. The cartels were not active in this area and the military had many checkpoints on the highways. Zipolite was sort of how you’d imagine California in the 60’s, people nude, openly smoking bongs, public showers available to all for pocket change. Affordable hostels, enlightening evenings.
I am sorry to hear of this shift. At one time, the original population of Mexicans was forcibly moved to government land which is arranged in a grid pattern, our guide lived in sector “U2” for example. You can see the grid where the local people live in google maps.
