Dance Haddonfield is the non-profit Delaware Valley Chapter of USA Dance, the national amateur ballroom dance association. Every Sunday at Grace Church there is a 7pm beginner lesson followed by 2 1/2 hours of open ballroom dancing. A large spread of food is provided to attract the guys and there is 20 feet of literature about local instructors, studios, and events in the Delaware Valley. About 60 people, mostly singles, show up every week. No notice required, just walk in. Cost is $15, the best deal in town.
