Reach 200 points for one jump in "Joe's Adventures."
As you drive through Westbank Steel in North Millville, you will come upon a ramp as you head toward the mission marker. Hit this ramp squarely going about 100 mph and you should get it. Hit it too fast and you will overshoot the landing and crash, too slow and you won't get the necessary 200 points.
You have to land without crashing for it to count. It may take you a little practice but the mission gives you plenty of time to retry it a few times.
