Growing up in Virginia I'd never heard of this (we did play pranks on Halloween to those who weren't generous with the "treats" or who gave us healthy items like apples when we wanted candy). But in Palisades Park, New Jersey where we lived during the mid eighties/early nineties my kids discovered the local custom of Cabbage Night. I came home from work one evening and about a block from the house I caught them trying to sneak home with several cartons of eggs that they'd gotten from a local store (some refused to sell eggs to kids at that time, others were more than happy to oblige). Of course the eggs were promptly confiscated but there WAS a lot of minor mischief perpetrated in the town on Oct 30th - soap on car windows, toilet papering, etc.
