HATTIESBURG, Miss. (WDAM) - A bit of dancing to six hours of tunes, mixed up with a feast of mudbugs, corn and taters among family and friends. Welcome to the 26th annual Downtown Crawfish Jam Music Festival. Presented in part by Southern Beverage and hosted by the Hattiesburg Historic Neighborhood Association, Saturday afternoon’s event at Walthall Park served as the largest fundraiser for the Walthall Foundation.
