I'm really sorry, but I've no idea what these are. I can hazzard a guess that it's some kind of housing for people who are out of work? I didin't think US had a benefits thing like we have in UK do they? aka get money from the State to live on if you have none? Have to be 'means' tested or made to apply for jobs before getting any hand out?

I really don't know. I realise I seem ignorant, but I also thought a 'trailer park' (apart from the disparaging comments made about them) were just places where people lived in caravans ... cos either they want to or can't afford anything else.

Don't know why I'm typing all this - think I better shush, but I'll post it anyway just to see the response.
