Enlist the services of a professional tarot reader, sometimes called a medium, for an unforgettable activity at your Halloween party.
Booking a medium at this time of the year may be difficult so plan early. Consult with the medium in advance, and she will let you know how many readings she can comfortably complete in an hour or two. If the number of guests exceeds the number of readings, hold a raffle to determine the participants.
You can find mediums online at MediumFind.Net, on Craigslist under the Services/Events" banner, the back pages of local entertainment newszines, or in the Yellow Pages (look under "psychics"). Inevitably in any group of friends, someone is bound to be a tarot reader.
