This isn't exactly a savenger hunt but it takes some hunting! One volunteer event I had the volunteers find info on each other. It was set up somewhat like bingo. There were a variety of questions e.g. A volunteer who plays the banjo (?)or a volunteer who has 10 kids (?). The volunteers had to mix and mingle to ask each other questions...when the volunteer matching the question was found they initialled the square. The volunteer who had there card filled first won a price. Everybody won though as they had a great time finding out about each other.
