Go on to the rainbow rail set a marker and try enough times and you'll fly out to the BC, then you can land backseat in order to get speed to cross the flats. Really fun stuff out there.
how are you guys gapping the left cliff to the box? i set a session marker at the end of the flat down to the very left and im always not getting enough speed
a little thing that would make the game a lot more realistic is to make the riders head always face down hill when spinning. except when he's backwards of course. just so it looks like he's spotting his landing.
