Twin Cedars High School Junior Lindsay Hoehns won the state championship in the class one-A girls long jump competition at the State Track and Field Meet yesterday in Des Moines.  Hoehns' best jump was 17 feet three-and-three/quarter inches.  Also for the first time in 25 years a Knoxville girls tennis player has qualified for the state tournament.  Evan Tonda placed second at the Regional yesterday in Boone and that automatically qualified her for next week's state meet in Johnston.
