No, doesn't bring out the worst in people here. Very conservative heavy-Mormon area where I live. Lots of small Christian churches doing 'trunk-or-treat' instead of the traditional trick-or-treating. I had to laugh last year that many of the churches were having 'harvest festivals' to get away from celebrating 'evil' Halloween.... what made me laugh is that the pagan origins of the holiday were: the final HARVEST celebration!!! so the churches, in an effort to steer away from pagan holidays, actually went deeper to the roots! Of course, their harvest festivals had nothing to do with actual harvests because food apparently comes from God, and not the earth....
ah, but I'm off on a tangent now, aren't I!~

No, it's pretty quiet up here.
What I have noticed is that it has become a 'greedy' holiday: parents drive their kids by the van-loads to the wealthier neighborhoods where they give out 'better' candy. Or they drive them to new subdivisions where the houses are more condensed so they can get more houses in less time! Astonishing to me. Confusing. If you want candy that bad, why not just go fork out the $2.50 and buy a bag? and... do the kids really NEED that much MORE candy???
I keep it a community thing where we only trick-or-treat in our neighborhood, visiting people we know. And the houses up here are TWO to an acre- with a few remnent farms along the way - (not six to eight like the more modern subdivisions), so the kids really have to walk to earn their candy! Then I trade it out for non-candy items that they can eat at their leisure, won't get sick from, and I dont' have to police them over it (popcorn, nuts, low-sugar-cookies, pencils/erasers, tattoos, etc)

so, that's halloween from Beautiful Boise Idaho.
