SAN FRANCISCO (AP) — Two brothers from San Francisco say they have set a record for the longest highline ever walked in both Yosemite National Park and California, the San Francisco Chronicle reported. Earlier this month, they and a group of friends spent nearly a week stringing a single, 2,800-foot (853-meter)-long line from Taft Point west across a series of gulleys that plunge 1,600 feet (488 meters).
