Kalan should ride Roadrunner Express because he already rides planes and Roadrunner at Six Flags Discovery Kingdom is a kiddie coaster. He even rides scary things like gyrocopters with open cockpits. Please make the comments positive and encouraging to support Kalan in his journey of overcoming his massive fear of rollercoasters. I and everyone who knows Kalan know that he is definitely brave enough to conquer the Roadrunner. Every signature counts. Thank you, sincerely. 

(He's not afraid of heights, he's not afraid of speed, he's not afraid of g-forces, and he's not afraid of the lack of control.)
