Slack - On the line 

Slacklining is the act of walking on webbing suspended between two objects. Like life it requires focus, balance, and the ability to overcome being on unsteady ground. It is a pure form of individual expression that is quickly catching on around the world. REI presents a look at the upstart sport of slackline through the eyes of three young professionals from Gibbon - Josh Beaudoin, Hayden Nickell, and Frankie Najera.
