On a recent family camping trip, I brought along a Gibbon Slackline I picked up from The Clymb. (Note: if you’re an adventurous type and like good deals on great gear, do yourself a favor and join The Clymb—it’s free).
I set it up between two trees, and over the course of the weekend almost everyone gave slacklining a try—kid and adult alike. Despite numerous strategies and techniques (fast, slow, sideways, tightrope-walker style), no one could really get the hang of it except one of the kids who has mad skateboarding skills.
He does wear a parachute, though.
