Families who arrive early for the Tennessee Aquarium’s AquaScarium VII Halloween party will get an extra special treat - the chance to see someone walk a line suspended between the Aquarium’s peaks.Local world-class highliner Edward Yates will rig lines of great heights on the Tennessee Aquarium peaks and then walk across them as a unique feature of RiverRocks 2014. Similar to tightrope walking, but accessible to anyone, slacklining and highlining are trending outdoor sports. Edward will safely execute this stunt in the common style of highlining and will be wearing a safety leash in case of fall.
