A good and positive representation is very important to Grand Master Dae Shik Yin and his instructors in the Valley.  After the July Yin’s Tae Kwon Do Academy has had, Master Yin certainly does not need to worry about that anymore this summer.  Master Yin had students competing at the Junior Olympics in San Antonio and at the inaugural Women’s International Tournament in Los Angeles in July.  The Academy was also represented well by a demonstration team of 12 women who made their debut at the International Tournament.  “Collectively, it was a very important stance,” said Dave Reynolds, an instructor for Yin’s Quartz Hill School.  “The women were such a dominant force and this demo was big for us, to do something major like that. And all 10 students competing at the Junior Olympics come home with medals.”   From Olympic hopefuls to fun-for-it competitors, Yin’s sent 30 female students -- of different ages and abilities -- to compete at the International Tournament July 6-8 at the Los Angeles Memorial Sports Arena.  Kathy Ledgerwood certainly made her impression on the Tae Kwon Do world this summer.  Ledgerwood fared very well at the International Tournament and as a member of the demonstration team. But was the only student to travel and compete in the Senior Nationals in Colorado in May.  In 2000, Ledgerwood has picked up 10 golds and one silver medal in six tournaments.  “I really didn’t think I would do this well,” said Ledgerwood, a 48-year-old deputy black belt.  “I’m just having fun and I’ve loved all the challenges.  Never in my wildest dreams, at 48, did I think I would be doing this.  It’s wild.”  Ledgerwood won a gold in sparring and gold in poomse (forms) at the International Tournament.  At the Nationals, held in Colorado Springs May 12-14, she finished first in sparring and second in poomse.  Ledgerwood, a minister at the Lancaster United Methodist Church, won gold at the San Diego Tae Kwon Do Championships and two golds each at the U.S. Gold Cup at Antelope Valley College, the State Championship and a Valencia Tournament. She was part of the first women’s demo team she has ever seen, but it was the participants at the International that made Ledgerwood so excited to be there. “It was great to see so many women show up and compete, even at my age category,” Ledgerwood said. “A lot of women are training, but they may not come out.”
