I heard of such a camp..where they had generators set up and everything else. It would beat the abandoned houses. Fred told me that crimes took place in the abandoned houses.. violence and beatings.. people robbing one another of the meager things they already have.
There was also a camp down at the end of Independence Avenue, where you get on I-35 to cross the Bond Bridge. Actually- they had it set up pretty comfortable, but the city booted them out of that one too.
They had people sleeping on the sewer covers- city booted them.
People treat one another worse than they treat beasts.
