We don't exactly do Halloween where I live, but pumpkins abound (not usually carved; we like to keep them to cook with through the winter), and the intentional community of which I am a part usually has a rather festive ghost story reading/ghost song singing party on or near the end of October.
The party is on the 27th this year. It will start with a stone soup supper at my house to which we will all donate the last of our garden produce. The party will then progress to a neighbor's residence (we're all on the same piece of property, so it's a short stroll) for the performance portion of the evening. Fire jugglers will entertain between houses, assuming there's been enough rain that there's no fire danger.
For that event my favorite song is Tabster's extraordinarily eerie "Song of the Knife" and my favorite ghost story -- not the teensiest bit scary -- is Richard Middleton's "The Ghost Ship." (Here is a Project Gutenberg link to the story.) I may cast about for a new story to read this year, but I find this one so perfectly crafted that I usually don't bother to find a new one. No one ever seems to mind hearing it again!
We don't bother with trick-or-treating in our 10-household community, but because I love the Persephone associations, I always have a pair of pomegranates on hand to give to the two teenagers who live there should they happen to show up. My own 7-year-old can go to a nearby town where the merchants do a trick-or-treat thing, if he wants to show off his costume -- but even he isn't wild about the mob scene and we may not bother with it this year (especially as I'm flying out to the Getaway the next morning). The treats we make at home in the autumn are more satisfying (and WAAAAY more healthful) than the candy bars the merchants give out, anyway.
