I have become oddly comfortable in and around casinos after 10 years of covering fights in Las Vegas. So congratulations to my friends at MGM Resorts International for securing the go-ahead to build a casino at National Harbor in Prince George's County, and many thanks for their consideration in building it a brief trip-down-King Street-and-water-taxi-ride-across-the-Potomac from my home. Planned opening: mid-2016.
