The Meadowlands and Monmouth Park, the racing properties of the New Jersey Sports & Exposition Authority, have applied for 141 Thoroughbred dates for the 2004 racing season. The request represents a substantial increase over the 120 Thoroughbred racing dates offered by the sports authority this year.The proposed dates were submitted to the New Jersey Racing Commission, which will meet on Nov. 5 at its Trenton offices to consider the matter. Thoroughbred racing at Monmouth Park would open Memorial Day weekend (May 29-31) and settle into a Wednesday through Sunday afternoon schedule in June through closing day, Sept. 5, for a total of 72 days. Then the Thoroughbred scene shifts to the Meadowlands for 69 dates from Sept. 6 through Dec. 11. The schedule calls for racing on Tuesday afternoons and Wednesday through Saturday evenings.
