When I lived in New Orleans, Hallowe'en was a big deal. Obviously in a city well-known for Voodoo, zombies, vampires, ghosts, and so on, it's bound to be.
One year we'd all planned to go out to nightclubs, and wouldn't be home, so we didn't prepare candy. The trick-or-treaters began to arrive earlier than expected, and after the first couple of kids were turned away (even with all the lights off, the kids still knocked) we had a rather large group arrive. Now, the children in NOLA can be a bit tough in some neighborhoods, and it won't go over well to deny them candy. We tried to politely turn the group away, but they became hostile, and surrounded our home, banging on the windows and doors, shouting, and throwing rocks. We were genuinely frightened that they would cause some real damage. So to diffuse the situation, I ran around the house trying to come up with whatever I could to give them, which wound up being paper bags filled with coins, macaroni, sticks of gum, and other odds and ends. It worked!
The tradition among our crowd was to head to Metairie cemetery on All Souls' Day for a wine and cheese picnic. Metairie is an absolutely gorgeous cemetery filled with luxurious mausoleums. Of course we did tend to shock a lot of the visitors, given that we were a bunch of goths. More than once we were kicked out.
