Yes to both. Round here it tends to be a school-related activity. Usually a small group of kids with a couple of parents, and we all tend to know who lives where ... so we'd walk the streets round the school, trying to get the kids to save the stuff rather than scoff the lot straight away, and we'd keep going until we had to taser the little devils who by the end of the evening were strung out on sugar and all manner of additives! As I say, never happened when I was a kid. I can't remember Halloween being a big deal in my teen years. It seemed to pop up suddenly during the 80s when my girls were at school. Maybe it was films like ET ('82) and TV shows like Happy Days (70s-80s) that introduced American culture to the UK audience? I dunno.
