Secret Cannon
Enter the Baja race, go towards the outer
walls. While gaining speed, lean back and
keep going towards the wall. If you can get
to the top go away from the cliff. You will
be shot into the air like a cannonball. You
will sound like one too.

Wall Jump
In National, head off the course, straight as possible. When you come up
to the wall make sure you are going at least 70 Mph. and go straight up the
wall. This is the only way you can get up to 100 Mph. If you continue
forward when on the cliff, there will be an explosion sound and you will go
about 100 feet in the air.
