Geena scored 24th place out of 300 women who tried out for the U.S. Olympic archery team. Although placing 24th out of 300 is an impressive feat, she did not make the team and wasn't able to achieve her dream of competing in the 2000 Sydney Summer Olympics. She did end up participating in the Sydney International Golden Arrow competition, though!
