The surfer was getting dangerously close to the crest. It was a huge wave, spanning 34 feet, but the last thing he wanted was to bail in front of his friends. Leaning into the water and weaving side to side, he kept his balance for just a few moments longer before tumbling onto the soft mats and safe bail area of the Flowrider. He'd be ready for the real thing come summer. This is just one of the adventures that await thrill-seekers-in-training at the Salomon Center. Away from the Flowrider's manmade surf, top-rope belay systems cradle climbers as they scale iRock's craggy, gray peaks. Incorporating holds that change monthly, these indoor climbing walls shoot upwards to heights of 55 feet. Alternatively, bouldering areas stay closer to the ground and exchange ropes for padded surfaces. Meanwhile, iFLY exchanges footholds for a column of high-speed, shooting air, which elevates would-be fliers to simulate the feeling of skydiving or being kicked out of a moving UFO.
