I have thwarted nightly pick-pocketing attempts on my recent trip to Boca Chica, Dominican Republic.
On the way from the main restaurant area to the disco, there is a dark area for about 30'. Every night, many women await men there and attempt to take money while groping solitary walkers. One cannot avoid them: One must push them and their hands off oneself. I could feel their hands attempt to get in my pockets, but they had problems with the zippers. Only one woman figured out the zippers; but, by that time, I had pushed her away and zipped the pocket back. I've never encountered such a nest of thieves, but I came out with my money on the other side everytime!
