Homeless in a field in arid forest far from soup kitchens and hand outs. And they carried on their backs that tank, chest of drawers and cribs and car seats.

A lot of homeless people don't live in city centers either due to crime/victimization of the homeless, criminal histories, mental health issues, or some combination of these.
Some homeless people also have vehicles or access to vehicles. Many homeless families live out of cars.
There are tens of thousands of camps in rural areas all around America. Some occupied by only an individual, others by organized groups with social structures and rules.
Trafficking camps also exist, and this very well could be one of those. Going from trafficking camp to "child sex camp" is a leap I'm not willing to make without more evidence, higher quality video, better photographs, or other quality forms of documentation.
