The wonderful thing about this fire festival is that you can celebrate it on the 31st, on the day before, the day after, all week or all month. There is Halloween for the kids (and the kid in everybody), All Soul's Day for the Christian mystics among us (and there are lots) and Samhain for those of us on the pagan path.
You can be as open as you want, everybody wants to believe on Samhain. I will be setting a table for the ancestors, handing out candy to the trick-or-treaters and later enjoying a ritual.
My favorite farmstand says they had to hire extra help this year to get the pumpkins ready and the corn stalks bundled.
