Do you ever see the dump trucks come along to collect trash in commercial dumpsters? The forks reach out and lift it high into the air above the truck and transfer the trash inside to the cargo hold? Well do you also see stuff flying out of the dumpster and not land inside? I do so here is what I recommend that you do. Get the phone number on the dumpster and call the company that services that dumpster. Let them know that you have seen this happen. Put both them and the location on notice that they need to do a better job containing the trash.
It will help keep the landscape cleaner, the waterways less impacted by floatables.
