Challies has a good article on Halloween up - Challies Dot Com: The Inevitable Halloween Discussion The following seems to be a good tact to take:

"The truth is that I have several convictions regarding Halloween. I despise the pagan aspects of it. I am convicted that my children should not dress as little devils or ghosts or monsters. But I am also convicted that there could be no worse witness to the neighbours than having a dark house, especially in a neighbourhood like ours which is small and where every person and every home is highly-visible. We have nothing to fear from our neighbours or from their children. So my children will dress up (my son as a knight and my daughter as a princess) and we will visit each of our neighbours. Either my wife or I will remain at home, greeting people at our door with a smile and a handful of something tasty. If the kids are deemed too old to trick-or-treat, they'll be forced to sing a song to merit any handouts. Our door will be open and the light will be on. And we hope that the Light will shine brightly."
