Put on your best Halloween costume and join us for a lively street dance party with live music right in the heart of Columbia State Historic Park! Groove to the sounds of The Lack Family Band as they play hits from the '70s to today’s favorites. This family-friendly event also features fun activities, a beer and wine garden, and delicious street food. The party kicks off right after the Boo Boulevard trick-or-treating, parade, and costume contest (2pm-6pm). Bring your lawn chairs and a good pair of dancing shoes! The event takes place at the intersection of Main and State Streets in historic Columbia. Free parking, free admission. Presented by the Columbia Chamber of Commerce and generously sponsored by Blue Mountain Minerals.
