Battle Ground -- The May 17 Relay for Life walk/run on a quarter-mile lap around Tukes Valley Middle School accomplished a number of things. Primarily, it earned $2,172.25 for the American Cancer Society. But it also honored the memory of Kristi Thiessen, a math intervention specialist who taught in Battle Ground schools for 30 years and died of breast cancer in 2010. Plus, it also encouraged exercise and fought the growing scourge of childhood obesity. Fifth-grade teacher Meda Logan organized the event with lots of parent volunteers.
