Young men and women arrived at Show-Me Gynmastics in Columbia, Mo., on Thursday, Nov. 29, 2012, to slackline during a scheduled Mizzou Slackline Club practice.  After setting up the slacklines, the daring group of college students began to test their balance by carefully walking across the gym, several feet above the ground.  While the fear of falling scares some, the thrill of the walk rewards others.  The club meets at the gym every Thursday at 9:00 p.m. Video by Katie Medlar.
