Members of the Iowa National Guard visited Fairfield High School Monday and brought with them a few toys, such as a zipline, humvee and a Dale Earnhardt Jr. promotional race car, which the National Guard sponsors. The zipline ran nearly the entire length of the parking lot west of the school. Sgt. First Class Jesse Howard, Staff Sgt. Scott Neff and the other soldiers in attendance erected the zipline platform on the south end of parking lot. Students were fitted with a harness on the ground before they walked up the stairs to the top of the 50-foot aparatus, where their harness was hooked into a pulley that ran along the wire leading all the way to the north end of the parking lot 220 feet away. Members of the Iowa National Guard tour high schools around the state, taking with them their rock-climbing wall for use in physical education classes. Howard said the Iowa National Guard also leads high school classes in “Warrior Fit,” a Crossfit cardio workout, as well as career direction and world history classes. On Monday morning, four soldiers demonstrated an exercise whereby they formed a square by laying on the ground with their legs on the backs of the person next to them, and proceeded to do push-ups simultaneously. After the soldiers’ demonstration, the students took a turn doing the same thing. Howard said the exercise is a great way to teach teamwork. “It’s not about you; it’s about what you’re doing to help someone else,” he said.
