Have any of you tried zip-lining? I went for the first time last week and it was really really fun. I looked around MacRumors and spotted only a few mentions of zip-lining in the forums: iBookG4user wanted to try it and KameronBriggs did. You ride under a hanging cable while attached by a harness to a removable trolley that rides the cable. Gravity takes you down and your body position controls the speed. Body position, a braking system, the leveling out of the cable, and springs at the end of the line bring you to a stop. Photos Me suited up: I went on five zip-lines, the longest being this one, 2800-feet in length over a canyon. The view from the top: Me on the way down. Leaning back with legs extended gets you maximum speed. Springs at the end of the line: I'm ready to go again the next time I have the chance!
