I heard on the radio about a man who has reduced the amount of fizzy drink consumption in poorer areas, not by protesting, but by creating an alternative. He's supplied houses with free water coolers. The kids think it's so 'cool' to drink from these, and their friends come round for drinks. Fizzy drink consumption has plummetted, and water consumption gone right up.
This is the principle behind Kiwi Halloween: creating a positive alternative, that people love so much they naturally want to do it each year as autumn deepens and pumpkins, apples and kumara have been harvested.
