An attendant was stationed here to help participants and ensure their safety. An informational plaque sat on the table and detailed the origin and history, as well as the amazing variety of superstitions having to do with broken mirrors. An information sign is displayed on either side. If instead you have real horseshoes to use you may simply want to hang these upside down on poles that guests pass by. Another idea is to actually have a horseshoe game alongside the course that participants can play.
Attendants can simply toss a horseshoe as they walk by, trying to get it around the poll.
Winners could receive a prize or extra raffle ticket if they successfully toss the shoe around the poll. You can also include a person disguised as a black cat running in front of people as they walk for both the obstacle course and throughout the larger event. Just after Hallowe'en you can usually find black cat displays at many of the supermarkets and party stores for a cheap price or, you can easily make them yourself out of black bristol board. The next obstacle included blocks of stone that you would normally see on a pathway. If the course is setup on a sidewalk it may be very likely there are already cracks in the cement that could be used for this particular activity.
