It's a Friday in Minnesota, and that means tonight's a good time for a meat raffle.It may be a part of Minnesota culture, but to newcomers and out-of-towners, the meat raffle baffles. As "Eat, Pray, Love" author Elizabeth Gilbert observed in the New York Times after visiting a Brainerd meat raffle in 2006, "You know you're an outsider when something that seems perfectly normal to everyone else is impenetrably bizarre to you."Meat raffles are considered a form of legal gambling, and they're regulated in this state by the Minnesota Gambling Control Board. They are common in Minnesota and Wisconsin, as well as in Canada and England.
