I picked option #3.
Oops? I don't know. I had this vague thought of how cool a pumpkin would look with an ornate Orthodox cross carved into it, with the light of a candle inside making it glow.
But now I have read your posts, and I should probably respond.
My reactions are quite ambivalent. I loathe the demons, witches, and so on, but I also hate the knee-jerk antipathy of my Protestant past. I was one of those kids who was forbidden to go trick-or-treating. I must have been about 10 or so when the evil roots of Hallowe'en were revealed to me. But then, Santa Claus was equally foreign to my family. Now I tend to feel that children need a few holidays, something to get excited about. If they have Orthodox parents who give them all the Church holy days, then they won't feel much need for the secular holidays - I think (some parent want to test this theory?).
In the meantime, we would best off avoiding costumes of evil origin (ie. witches, devils, Bush, etc.) and costumes that completely conceal the face (more mischief is performed under conditions of anonymity...). Candy consumption can be curbed, and the children guided to safe districts, like friends' homes. This to me feels like Christianizing the holiday. Cleansing it a little. Oh, and don't decorate the house and/or yard to resemble a charnel-house. It isn't very joyful. My two cents.

PS. When I say Christianize, I would like to caution against what a Baptist church did when I was a kid. They encouraged all members to bring their children for light snacks, games, and a little protective prayer. Oh, and dress like a biblical character. (I remember that I was St. Philip's Ethiopian.) The Sunday School superintendent's son came in dressed as the demon-possessed Gadarene - you know, the guy called Legion. Obviously, somebody had being paying attention in Sunday School. Needless to say, this felt to many to be completely missing the point. What is it about costuming that brings out the worst in us? Maybe I will need to make a new post. Later.
