Two San Francisco brothers claim highline record at Yosemite

Two brothers from San Francisco say they have set a record for the longest highline ever walked in both Yosemite National Park and California. Earlier this month, they and a group of friends spent nearly a week stringing a single, 2,800-foot-long line from Taft Point west across a series of gulleys that plunge 1,600 feet. 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 balance beam.
