Beat me too it. I am just now planning a trip south Vesta, did you know there are actually dump stations at rest stops on some major highways heading down south?
Did you know you can dump ( for a fee of course ) at the Pease sewer plant?
Geeze Louise get with the times.
Did you know bums let it all hang out all over Pee_town? (of course you did if you ever been near Gilly's the morning after the night before
)
(Of course there are great stories about the habits of long haul truckers and others told by those who maintain the highways an by ways of this great nation but we won't go there. Hint: That ain't a gallon of apple cider they are throwing out the window.
)
Get with the program young lady, don't make me get out of this chair!! 
BTW Squatters? Nice word but the image that invokes, the image. 
Times have really changed ,Everything is upside down today Lovey, very odd.
At one time if one needed to disappear they headed for the wilds.
As those idiots who were caught this week at a camp site, the escaped Convict and his girlfriend/cousin found out, they went the wrong way.
Had they gone to a big city they would just have blended into the scene, unless they did something really outrageous they could have survived in the city for years.-----
Back on subject, the Squatters go mostly unnoticed in a city, people avert their eyes from their shacks and those that live in their cars. Few cops have the time to question them and when they do unless the people have an arrest warrent out on them, they find most of these people are mentally ill, homeless or unable to function on their own due to some addiction. Sure they can scoop them up [ Soylent Green comes to mind ] but then what do they do with these people.???
Take a ride from Boston to Washington DC. on Amtrack, OH MY, an eye opener as one looks out the window at the burnt out buildings that have satellite dishes and air conditioners in the windows. Some of these abandoned factory's from the early 1900's even have gardens planted on their flat roofs. I recognized a few chicken coops up there where at one time people raised pigeons for food.
A documentary I watched showed a thriving life style under NYC. Sub Way System. The squatters dragged in material to build shacks down there, found a way to tap into the electric lines, found a running sewer to use for a toilet and even a broken water pipe that people could wash their cloths and shower under. The city came in and destroyed their homes and placed the people in small apartments with hot water, and a kitchen.
They got food stamps and welfare, were they content.?? Hell NO most of the people were not happy as they were bored and had no reason to get up in the morning. 80 % of the people just walked off and found another space under the city to set up shop.
We have a multimillion dollar homeless shelter about 5 miles of me, at one time the police asked them to let them know about their new residents as they kept finding sex abusers living next to a family with kids. The shelter threw a shit fit, and refused to turn any information over to the police. ----IMO I think they need to keep the beds full in order to show a need for donations---
