i had a great time, whenever little 13 kids started chucking eggs at the house because we didnt give them any sweets i ran out after them shouing with a baseball bat. the look on there faces is much better than walking round in the cold knocking on doors. IMO trick or treating was ruined with mischief night (in the UK anyway)- this is the night before halloween where the local kids embark on mindless vandalism, mainly chucking eggs so that people are more likely to give them stuff the next night.
I dont think trick or treating is a good idea- it might be differant in the states but here it has changed from a bit of fun for the whole community into yobs going round and threatning old ladies with violence and vandalism.
