I was at the Winternationals when the Boston Shaker crashed. My dad filmed it- after the wheelie, the car came down & snapped the front end. It careened into the other lane & hit the guardrail, where the body flew off & the rear end with both tires still attached cartwheeled down the track. Kosty ended up right in front of us, strapped in the chassis, engine still running. I've gotta find that footage!
