I hope the keep them from doing it. Total $hit. They roll trucks down the road our road dredging it out and thinking no one knows at 4 or 5 AM when they roll by. Look at the beaches over here an see how far it has receded...
In order to stop this practice, they would have to execute extra-judiciously some of these truckers and burn their trucks in plain sight for all to see that if they continue this practice there next. They were given a warning about the executions. Since we all know the Trujillismos of the past are long dead for the most part, sand will continue to be hauled away.
It'll stop for a time and then just as the tide, it will come right back. Burning the goods and executing the perpetrators are savageries of the past but they were darn effective at least within the DR. The crooks know the law don't mean business so it'll be the usual cat and mouse game. It will continue until they permanently destroy the environment.
There always seems to be a lot of activity on the highway when I go through GH to get to Playa Grande, Its usually a bunch of people with a rope across the road looking for some pesos. I pay up and roll through.
