ARLINGTON HEIGHTS, Ill. - The trainer with the largest 2-year-old operation in Illinois has 25 stalls at Arlington, but all those unraced young horses are way downstate at Fairmount Park. The same trainer conditions one of the best 3-year-old fillies with Illinois connections, but upon easily winning the Grade 3 Miss Preakness Stakes last weekend at Pimlico, Palanka City was sent not to Arlington, but on to Prairie Meadows.
