Organizers of the Brewer Riverwalk Festival are already planning next year’s festival after the inaugural celebration on Saturday drew more than 500 attendees. In addition, local crafters who sold their wares during the event are calling for the festival to become an annual tradition, as Saturday’s event generated widespread business and interest in the city’s downtown. The daylong celebration of Brewer’s Riverwalk, a mile-long riverfront path, featured food trucks, children’s activities and live performances.
