Southern Columbia Area High School students in Claire Campbell’s gym class on Monday had the opportunity to play “knockerball” where they each donned a giant, inflatable ball and spent the period running into one another and bouncing around the school’s gym. Theywere to play a game of soccer while wearing the inflatables, but each class devolved into a free-for-all. The activity was brought to the school by Staff Sgt. Steve Meisner and Sgt. Leslie Morris of the U.S. Army National Guard, Danville. The National Guard brings several activities to Southern Columbia Area this school year, including a rock wall and, later this spring, a rope course.
