Become an amateur detective for an evening during this participant-driven fundraiser for the Rutherford B. Hayes Presidential Center. The Hayes Museum is the site of a series of history-related mysteries. Teams of participants compete to solve the mysteries, earning the most points and the right to the coveted "know it all" award. Detectives work in teams of eight- assemble your own team or we will partner you with  others. For information call 419-332-2081 or visit www.rbhayes.org
