Business is booming at Maryland’s casinos. The Maryland Lottery and Gaming agency says more than 162-million dollars was generated at the state’s casinos in April. That’s the third-best month in history and a more than eleven-percent increase over April of 2019. All six casinos were closed a year ago due to the pandemic. Revenue was up at five of the six casinos last month, with the Horseshoe Casino in Baltimore the only one reporting a slight decline.
