I used to dive and fish there a lot back in the 80's and 90's. Car topped either my 12' zodiac or 14' aluminum mirro craft in and just set up camp on the beach. Very different place back then, just families of fishermen, great people and always safe. Then something very wrong happened to the village. It became a place were many of the dregs of society hang (or hide out) and many of the good folks were pressured to move their families out.
I too went in there on a recon trip a few years back hoping for signs of positive change, but for not. Spent about half an hour walking around, checking out the ramp and talked to a few people. One guy was a LA gang member hiding out "on the lamb" in there from the states. He asked if he could buy one of our pass ports.....don't think so. We also heard that meth was a real problem in the community. Upon getting out of the truck a negative vibe from the area was almost palpable. We both really felt like we were not wanted and didn't wait long to head back to the highway.
Puerto Santo Thomas has a lot to offer when the situation in there changes for the better and hopefully soon.
