The OHA's Ghost Walk is a really fun way to get in the spirit of Halloween while learning a little about Syracuse history. Participants start at the OHA, where they are "briefed" by a detective who guests that their task is to spot ghosts around downtown Syracuse. A tour guide then leads guests on a walk through downtown Syracuse, stopping at various locations for guests to hear ghost stories told by costumed actors. My whole family, including my six year old daughter, really enjoyed this event and will definitely attend again
