Fairy Tale Extravaganza: Families are invited to help kick off the annual Fairy Tale Festival with crafts, magic, a giant knight, free pictures, and more all weekend at the Enoch Pratt Library Central Branch. Preschoolers can also attend a special ball on Sunday (1pm), so they should wear their finest attire or dress-up as a prince or princess, and enjoy live music, dancing, and crafts.
