This clip is of 'Ted Shred' a character in the vintage ski movie by Dick Barrymore called Canadian Mountain Odyssey. It was a flick made in the 1980's and in this scene features a vintage Burton snowboard (looks like an old Burton Backhill to me). It is said that Ted Shred aka Blake Barrymore was a natural on the newly acquired Burton snowboard. According to records the vintage Burton snowboard was purchased for $40 with the 'instructor discount'.
The video showcases Blake's ability to out ride skiers with his signature move...you've been "Streaked by the Shred Baron". It was shot in British Columbia Canada in the Monashee mountain range. I'm not sure about you but the last time we took our vintage Burton snowboards out for a few runs we had nothing on Ted Shred.
