Go to the "Bus Jump" level. Go over to the basketball court. The crash. You will start agin in front of a little mini ramp. Go up to the ramp straight. You will land on a bench. Then when you reach the end of the bench hit the accelerator to make it to the next bench. And when you reach the end of the second bench hits the accelerator again and it will boost you over the fence. There is a baseball field. The only other thing I found has been a ramp leading back to the basketball court. It is not a special trick. It is just fun.
