Tonight, Budweiser's Guns 'n' Hoses once again pits city and county firefighters and police officers against each other in three-round boxing matches. There's no malice here — the combatants are fighting for a good cause, after all. Proceeds from Guns 'n' Hoses go to the St. Louis BackStoppers, the group that provides financial support to the families of police officers and firefighters who die in the line of duty. Bouts start at 6:30 p.m. Wednesday, November 27, at the Enterprise Center (1401 Clark Avenue; www.stlgunsnhoses.com). Tickets are $17 to $22, and going very quickly — the first round of tickets sold out last week, but keep an eye on the website if more become available (you can always donate directly at www.backstoppers.org).
