NEW ORLEANS - Under lights early on a humid New Orleans morning, the Steve Asmussen stock whizzed around the Fair Grounds racetrack seemingly by the hundreds. But it was not hard to find the queen of the hive. Rachel Alexandra paraded out at 6:30, accompanied by assistant trainer Scott Blasi and Pancho, the most recognized stable pony in America. A few feet behind, astride another pony, came Asmussen himself.
