What are some good Halloween decoration ideas?

A lightshow

if some one is going to hand out candy, dress them up as some one scary, have the candy on their lap, and pretend to be a decoration. when/ if some one touches the persons arm, have them jump up and scare the trick or treater.(it also works on teenagers that steal all the candy.)

I love the purple lights. It gives off an errie, yet dark glow. You also can't go wrong with tombstones, spider webs, and skeletons. And a nice haunted sounds CD to play would top it off beautifully.

spider webs if u want real 1s thencome over and a real spider that can kill u and a somker or a goast hangie thingie. last 2 years the 1st house ,...... a real life snake thank god it was a pet
