I personally reported this group to the NJ DEP Hotline, they were out in broad daylight on Saturday Afternoon on Quaker Bridge Rd and other well-traveled areas. This video shows them in multiple areas that are signed off to motor vehicles, including First Beach on the Mullica River. One clip even shows them in the middle of what I believe is the Batsto River, possibly at Hampton Park.
UPDATE: This group of land abusers received a verbal warning. I am investigating how to submit this video as evidence against them. The DEP Hotline Dispatcher did not have a way for me to do that.
Here is another recent video from the Atsion Burn Natural Heritage Priority site from just a few weeks ago. This area is home to multiple endangered and threatened species and it is being turned into a virtual mudding arena.
