This is a highlight video of the Seventh Annual Carson David Ianson Memorial Quarterpipe Classic. Lover of shred, Carson David Ianson passed away in 2002. Five years later, his best friend and hand sculptorĀ  extraordinaire, Corey McDonald rallied the Boise scene to help shape and host the first CDI Memorial Quarterpipe Classic. Seven years later and the session has become a must-attend event on the underground transition circuit. The highlights of this edit made by Derek Weimer are Randy “Killer” Vannurden’s t-bag (frontside invert to fakie the hardway), Evan Williams’ backside five, Corey Mac’s alley-oop cork five, and Parker Duke’s shifty poke to fakie.
