How's that for balance? U.S. woman becomes first person to walk a slackline between two trucks driving at full speed

World record holder Faith Dickey, 23, performed the death-defying exploit on an empty stretch of motorway in Croatia, with no oncoming traffic. After fasting the tightrope between the two trucks, Miss Dickey limbers up and crosses the wire while both vehicles are still. But the feat suddenly becomes much harder as they speed along the fresh tramac, the central barrier of the road separating them.
 Crazy I think!!!
