Raiderette Kathy Ferrin has come a long way—from Los Angeles, where at age 24, she was a Raiderette in 1986-87, to Oakland, where at age 40, she is once again cheering for the Silver & Black. In fact, three to four days a week, she travels a long way. The Orange County resident commutes to the Bay Area for Raiderette practices, games, and mandatory public appearances. But perhaps her greatest journey of late has been the transition from mom to grandmom.
Kathy retired in 1987 from the Raiderettes to concentrate on being a mother, but she returned in April 2003 to regain a spot on the squad. On November 9, 2003, at the Raiders-Jets game, she cheered for the first time as a grandmother. Although the Raiders lost in overtime, she still had much to cheer about.
