The racing industry marked the one-year anniversary of the Sept. 11 terrorist attacks on the United States with various memorial services, including one that was simulcast to betting outlets around the country from Del Mar in California.Arlington Park, Delaware Park, and Turfway Park were among the racetracks that held their own services as part of their live racing programs. Belmont Park and Meadowlands were closed in honor of the anniversary.Del Mar held two ceremonies, the first of which was simulcast around the country at about 1:10 p.m. EDT. The National Thoroughbred Racing Association helped coordinate the simulcast.Among the highlights of the Del Mar program were a huge American flag that covered both the dirt track and turf course, and a video commissioned by the NTRA. The video, produced by Conover Tuttle, featured the song "Into the Fire" by Bruce Springsteen."We took a combination of still images from Gamma Press in New York, and melded that with slides from the Breeders' Cup ceremonies of last year," said Chip Tuttle, a partner in the Boston-based public relations firm. "We tried to find an appropriate piece of music, and thought the cut from the new Springsteen CD was particularly poignant."The ceremony was broadcast on the TV Games Network as well. The network went "dark" for a few minutes after the simulcast.
