Zak Maytum is one crazy fella.
A video has emerged online showing the Boulder-born longboarder racing downhill on his plank at speeds exceeding 70 mph.
Shot on a Colorado highway, the video shows Maytum cruising at full speed and flawlessly dodging oncoming traffic while maintaining his balance on the rough road.
One minor bump or one wrong maneuver could have had Maytum suffer critical or even fatal injuries. But oblivious to the potentially tragic consequences, this daredevil rode his plank like a boss.
Check out Maytum's madness in the video above.
