For some, Halloween is a day for running around the streets dressed in silly costumes. This whole Halloween schmozzle works well in parts of the US where this time of year is mild and pleasant. Here in the UK, by early evening temperatures will be close to freezing - which is why our own festival-of-this-time-of-year, bonfire night on November 5, is much more appropriate for being outdoors.
Don't get me wrong, though. I've nothing against Halloween itself. But rather than going out (or encouraging your children to go out) and freezing your toes off, I'd recommend staying in the warm and curling up with the traditional good book.
What to pick? If you haven't read it, my ultimate Halloween treat would be Ray Bradbury's Something Wicked This Way Comes - a superb evocation of the chill of fear. I re-read that pretty regularly, but my Halloween reading this year with be Neil Gaiman's Neverwhere. It was a good TV series, but in book form it is much better. Pass the bat's blood.
