Wilton seniors are invited to play pickleball at the Norwalk Senior Center, 11 Allen Road. Pickleball is a combination of badminton, tennis and ping pong played on a court the size of a badminton court with a net similar to tennis but not as wide. The paddle is made of wood or graphite and is like a ping pong paddle but larger. The ball is a whiffle ball made in Connecticut. The idea of the sport is similar to tennis but the serve is underhand. Norwalk Senior Center members play for free and non-members pay $40. Information: 203-847-3115.
