there could be a gap twice that but if it was to dirt landing and flying over dirt it wouldnt be nearly as badass props for taking such a massive risk!
i've stopped and looked at that thing almost every time i drive by it. Its totaly the first gap thats sketchy. The rock looks like a better tranny in the picture than it actualy is.
You drop on the rock face then the tranny, This line is between whistler and pemberton visible from the highway, theres actually like a sand pit area you can drive into there and look up the mountain side beside the highway. Alot of it is overgrown tho. Was also in one of the earlier NWD Richey Schleys part
