So, these aren't the hippie's with the "split wood not atoms" bumper stickers???
It does look like an excellent dirt bike riding area. It'd be great to ride a loud two-stroke right through the middle of the group. Then watch them cry over the freshly murdered grass.
Does any one find it funny that those earth loving industrial hating hippies have a high tech device like a video camera that seems to work well in the low light area of the jungle. There is probabley a prius parked a few hundred yards from there. I'm sure it is real.
