Silver Bullet at Knott's is like Harry Potter taking a pleasant little joyride on his broomstick. Tatsu at Magic Mountain is like Harry flying on his broomstick, chasing after the golden snitch with Voldemort on his tail about to devour his soul. For those of you unfamiliar with the Potter oeuvre, translated, that means: Tatsu is worse. So much worse. You hike up Samurai Summit to the loading zone, cram into a bucket seat. A brace comes down over your chest and ankles, and the seat tilts forward until you are in a variant of the yoga position Downward Facing Dog. At that point, the ride begins. Then it's dives, loops, zero-g rolls and pretzel loops, at more than 60 miles per hour. The Tatsu tracks pass over that of Revolution, which once was the only ride that did a full inverted loop, as if to say, "Oh, how cute. Look how far we've come in this world of making the human body do things it was never meant to do."
