Good question, and it probably depends who you ask. The advocates will sing the praises of a well run "rest stop", about how clean they are and how respectful the residents are. There are some land owners who are willing to allow "temporary" rest stops, and others who, for what ever reason, are adamantly opposed.
There are advocates of the homeless who don't give a rip how the neighbors feel and try to establish rest stops where ever there's a vacant lot. If you object, it's because you're evil, greedy, selfish, cowardly, cruel, and a pathetic excuse for a human being, and you don't  understand that homelessness is your responsibility to cure.
