Other than the elite thoroughbreds thundering over 1 3/16 miles of dirt, nothing about the 2020 Preakness Stakes will feel familiar. There will be no crowd of 130,000, no musical act blasting tunes, no drunken patrons stumbling to overtaxed portable toilets. There will be no traffic jam on Northern Parkway, no neighbors turning their driveways into paid parking lots, no gamblers racing to the windows at Pimlico to place last-minute bets. There will be no crowds at morning workouts as anticipation builds throughout the week, no Alibi Breakfast on Thursday to gather the competing trainers. NBC’s commentators will analyze the race from a studio in Connecticut. The pro-secessionist state song, “Maryland, My Maryland,” will not be played as race organizers embrace the social justice messages that have swept American sports.
