A dumb question to Cyburbians who live or have lived outside of the United States: do you have hoarders there? In my travels through Canada, I've never seen the "40 junked cars on a lot" phenomenon that is common in some parts of the rural United States. I know there's complex sociological and cultural reasons for visible hoarding in the US (Appalachian/Scots-Irish culture, property owners don't see their property as part of a larger neighborhood or community, the rural poor using junk as a source of income, etc), but what about other countries?
FWIW, around where I live, outdoor junk storage is illegal, but you'll see flagrant violations here and there in some more rural towns. It's mainly because the perpetrators are long-established families that are difficult to difficult to deal with, with a long-established reputation among local law enforcement officials; a live-and-let-live hippie mindset; and "tolerance" for Appalachian culture.
