Dangerboy Deegan Battles For The Win

Mammoth Mountain just wrapped¬†up its 50th running of the Mammoth Motocross amateur national, and as usual tons of action went down at the week long race. The madness on the racetrack was at an all time high, and this GoPro footage courtesy of “Dangerboy” Deegan serves as evidence! Check out this crazy come-from-behind performance from young Haiden as he races his way around¬†the mountain to the win.
