Temper Tantrum, Speedball, Hoochie Krypt, Whirlybird and Fakie.  What do these all have in common?  These are all insane wakeboarding tricks involving tricks, flips and spins all while rocketing up to 6 meters (20 feet) high off the wake of a boat travelling up to 56 kph (35 mph).  Not convinced this is an extreme sport?  Speak with Andrea Gaytan, four-time world champion wakeboarder who performed a krypt, which is a handstand in the air followed by landing backwards on the wake.  Give that a try.  Over the course of her career, Andrea sustained knee surgeries, a broken nose and herniated disks.  So, if you do it right, it’s extreme,  otherwise no points.
