One more thing....if you think these same people are not in legitimate campgrounds, you'd be wrong.
I see them in public parks, county campgrounds, private parks and in the woods off of trails. I can't tell you how many meth labs there are in the woods and the teachers in some of the rural communities have a name for the children of these "RVers" it's "feral children". I just about dropped a jaw when I first heard that term. According to the teachers they come and go, totally unpredictable as to when they may show up.
I don't mean to sound harsh, it's just the way it is. I'm not going to candy coat it and call it "homeless population" because plenty of these people are living this lifestyle out of choice. Sure there are legitimate homeless but that's a different topic.
