BALTIMORE - John Passero's workday for the Preakness on Saturday started at 8 p.m. Friday.
Passero, Pimlico's track superintendent, checked the weather Friday afternoon, did some calculations, and then radioed for his crew to hook up 10-ton rollers to the water trucks, fill the trucks with water, and get to the track. The trucks, which weigh 75,000 pounds when fully loaded then drove around the track, side by side, again and again, packing the dirt course to a tight seal.
