I simply refuse to participate anymore. It used to be harmless fun for kids....now, I get invitations to grown up parties (put on by the owner of a costume shop who expects us to rent costumes from her AND pay an admission fee!!), the older kids go out and be Vandals for a night, egging and worse, the drunks go to the bar so they can hit the little kiddies on the streets, etc.
I just turn out the porch light and hibernate in the back of the house. Say a few Samhain blessings, keep the animals indoors and go to bed early.
