The Jockey Club lost its fight in Annapolis to pass a bill that could have helped the company establish a “super track” at Laurel Park and perhaps eventually close Pimlico and move the second jewel in horseracing’s Triple Crown there. The company faced criticism for spending the bulk of its state subsidies for racetrack improvements at Laurel instead of Pimlico, and for the housing conditions of people who live and work on the backstretch.
