Well, we don't celebrate Halloween here in OZ. However, we're doing a letter drop down our street to see if anyone's interested, we know there's quite a few kids in our street. We're going to provide a sticker or a fridge magnet (for those with metal letter boxes) with an H on it to put on their letter boxes if they're going to participate.
As for a display? OH BOY, do I have plans, but it will be movie themed rather than traditional. I really hope the street takes to the idea.
Cheers,
Kraig
