I grew up in East Yorkshire and November 4th was mischief night. We would do all kinds of crazy things like removing peoples gates and hiding them, knocking on doors and running away - you know the kind of thing! The great thing was we never got into trouble, after all everyone knew it was mischief night and expected to get up next day and find their garden gnomes missing!!!
I live in the south of England now and no-one has heard about mischief night. How about you ? Does it happen where you live?
