Staff members at Quincy Community United Methodist Church dress as favorite characters, including Hagrid, Mad-Eye Moody and Professors Trelawney and Snape. Guests can explore Gringottâs Wizard Bank, Diagon Alley and the Great Hall. Members say itâs all in good fun and the pastor says it draws people to their church for the first time. âIn this day and age there are lots and lots of people who have never ever set foot in a church. We feel that the Harry Potter Extravaganza is a way to welcome people into our church.â
