Where I used to live in northern Wisconsin, they had the kids to Trick or Treat stuff early because people got fed up with the weather or sometimes early winter conditions.Do you amerikans (and kanadians? trick or treat on the hallow eve (30th?) or the weekend closest to it? I'm asking because this holiday has spread here over the last 10 years and we have our own all saints eve (alla helgons afton) which is pretty much the same thing except we haven't commercialized it like you have. We usually just light candles on dead relatives graves and not much else. But our holiday is the first weekend of November (no fixed date) which means it sometimes collides with Halloween and sometimes it's a week apart.... it's all really confusing for the kids coming up now, not having any idea of how and when to celebrate this imported thing.
Edit: Oops , there's a thread for Halloween... mods, please feel free to move this post?
