Milan McKay spoke with Steve Coats outside Citadel High School where Steve was practicing his slacklining skills. Slacklining is a balance sport that uses nylon webbing stretched tight between two anchor points. Slacklining is distinct from tightrope walking in that the line is not held rigidly taut (although it is still under a lot of tension); it is instead dynamic, stretching and bouncing like a long and narrow trampoline.
