If it's the night before Thanksgiving, it means some fights are going to break out -- it's tradition. The Budweiser Guns 'n Hoses boxing matches return for the 30th time at 6:30 p.m. at Scottrade Center (1401 Clark Avenue; www.stlgunsnhoses.com). Firefighters and police from the city and county departments square off in fifteen three-round bouts. These fights will raise money for St. Louis Backstoppers, the charity that aids families of officers and firefighters killed in the line of duty. Because of this year's nice round anniversary number, the evening has a retro theme celebrating Guns n Hoses 1980s origins, so wear your neon and make your hair big. Tickets are $15 to $30.
