This is a short video of Baja 100 racer Adrian 'The Wildman' Cenni performing a 360-degree barrel roll before a race in Ensenada, Mexico. They call it the world's first 360-barrel roll, but at least a handful of other people (including Rob Dyrdek) have done it before. I dunno, maybe he's the first one to do it without a landing ramp. Or maybe he's just the first one to do it where there was literally no regulation on where the audience could stand.
Keep going for the video.
Thanks to Shane, who has every intention of becoming the first person to perform a double barrel roll outside of Star Fox.
