The Elwood City Strawberry Festival is an Elwood City celebration that takes place annually, first appearing in How the Cookie Crumbles. There are many different events during the festival, including a parade. David Read had described it as "the biggest holiday of the year" until D.W. started asking questions. He then changed it to "of this week." It was revealed by Grandma Thora that the festival had always been David's favourite holiday. She had also said that there were always as many strawberries as you can eat.
