Prices tanking. Gasoline prices in western Wisconsin fell to a low that many people can’t remember: $2.72 at stations in Galesville. On the Minnesota side, some prices were even lower: $2.69 at St. Charles I-90 truck stops. Others: Kwik Trips in Winona, $2.85 to $2.91; BP in Winona, $2.91; Kwik Trip in Lewiston $2.85.
