In order to become an extreme sport, a regular sport must undergo a brutal hazing by the other sports that culminates in the ritual sacrificing of its common sense. Check out a haven for these dedicated athletic endeavors with today's Groupon for two indoor wave machine sessions at Adrenalina, located in the International Plaza. Adrenalina is a heart-pumping, action-packed extreme-sports retail store that claims to have the only in-store FlowRider indoor wave machine. A ride on the tubular water-coaster combines the giddy thrills of body boarding, wakeboarding, skateboarding, kite surfing, and snowboarding without the hassle of sunscreen or incurring the wrath of Poseidon. Once you've conquered the aqua-bronco and toweled off, shop for new death-defying duds amongst Adrenalina's wide selection of hard-to-find action apparel and equipment for almost every action sport, including skateboarding, BMX, mountain biking, surfing, and shark rodeos.
- The contraption blasts a sheet of water over a padded wave form at up to 60 mph to create a perpetual wave. It allows riders "to drop in on their own unbroken wave, feel the power and acceleration, carve a turn, do maneuvers and cut back," Adrenalina boasts on its Web site. The water is only about 2 inches deep, so wipeouts are simply padded falls. – Jerome Stockfisch, Tampa Tribune
