“Highlining is high-altitude slacklining, in which a narrow strip of strong, nylon webbing — usually an inch wide and a few millimeters thick — is strung between two anchor points and serves as a kind of dynamic balance beam. Completing a line means carefully heel-toeing from one end to the other while wearing a waist-harness that links to a 3-inch steel ring around the webbing. In a fall, walkers remain attached, but they have to haul themselves back up to balance or shimmy back to an anchor point while dangling upside down.” So why not do it for a half-mile stroll over Yosemite? SF Chronicle: Yosemite highliners claim record 2,800-foot air walk from Taft Point.
