A 14-foot blue rooster sculpture stands on the National Gallery of Art East Building roof while more than two dozen IndyCar drivers prepare for the Freedom 250 Grand Prix, a two-day event featuring a 1.7-mile irregular track on the National Mall. The race includes 147 laps, speeds up to 180 mph, and passes multiple Smithsonian museums and the National Archives. The National Gallery has boarded some outdoor works after conducting a vibration study; other agencies have not responded to inquiries.
