It is that time of year again when our little witches and goblins dress up and go trick or treating. This year it falls in the middle of the week, but that doesn't mean there is nothing to do. The Massachusetts Office of Travel & Tourism (MOTT) has put together a great list of places to go and things to do. If the children are going trick or treating, the local police set the hours. Here is a partial list of communities with the hours. For more information, check your city or town hall's website.
