Detroit (AP) - If smoking is banned in Detroit bars, restaurants and workplaces, Betty Gilbert says it will hurt the city's casinos. Gilbert, who was smoking a cigarette Friday with members of her bowling team on a sidewalk near Greektown Casino downtown, should know. The 69-year-old from Cape May County, N.J. - who said she usually gambles weekly in Atlantic City - plans to cut back when that city's smoking law goes into effect.
