 We're soon going to see the first steps toward renovation of the historic Pimlico Racecourse, the home of horse racing's Preakness Stakes. All racing and training will come to an end September 1st, and the horses are going to be moved to Laurel Racecourse while Pimlico is being overhauled. The state of Maryland took over Pimlico and created the Maryland Thoroughbred Racing Operating Authority. That authority is going to oversee the renovations at Pimlico. The Baltimore Sun reports the engineers are still working on the timeline for when the old grandstand will be coming down.
