For 31 years now, area police and firefighters have gathered on the eve of Thanksgiving to raise funds for the families of their fallen brothers and sisters. Guns 'N Hoses features police fighting firemen in three rounds of boxing and mixed martial arts, with the proceeds from ticket sales going to Backstoppers, the organization that helps the families of first responders killed in the line of duty. The bouts may be for charity, but both teams want to emerge victorious; none of these men and women will throw a fight. The 2017 edition of Guns 'N Hoses takes place at 6:30 p.m. Wednesday, November 22, at Scottrade Center (1401 Clark Avenue; www.scottradecenter.com). Tickets are $12 to $32.
