Friday, August 3: Are you a bride in search of a dress? Are you a thrill seeker unafraid of death by trampling?

Starting at 8 AM, hundreds of brides-to-be race one another through the department-store doors in their quest for the perfect dress. Not for the faint of heart—but an event unlike any other.
