Ride all the way to the tall mountains in the Stunt
Quarry and get on top. Keep going around without hitting the invisible
wall that blasts you. As you get to the corner at the top of the
mountain keep pressing [Tab] every time it blasts you.
Note: You must be precise when repeatedly pressing [Tab]
immediately after it blasts you. If done correctly, the screen
will turn white and you can still ride.
