Arabians are mascots for football teams, performing crowd-pleasing activities on the field and sidelines. One of the horses who serves as "Traveler", the mascot for the University of Southern California Trojans, has been a purebred Arabian. "Thunder", a stage name for the purebred Arabian stallion J B Kobask, was mascot for the Denver Broncos from 1993 until his retirement in 2004, when the Arabian gelding Winter Solstyce took over as "Thunder II". Cal Poly Pomona's W.K. Kellogg Arabian Horse Center Equestrian Unit has made Arabian horses a regular sight at the annual Tournament of Roses Parade held each New Year's Day in Pasadena, California.
