Instructions
Select the Los Angeles level from the Level Select menu.
Turn left as soon as you start the level. Skate toward the rail closest to the building in front of you while holding the "A" button. Release the "A" button to jump when you get close to the rail. As you land, press and hold "Y" to grind. Keep your balance by pushing the joystick left or right as needed. Press "A" to jump off when you are near the end of the rail. Land with your skateboard straight and roll away to get credit for finishing the trick.
Turn right at the street and follow the sidewalk until you reach the movie theater. Repeat the process from Step 1 to grind the rail in front of the theater.
Turn right again and grind the rail in front of the library.
Skate through the passage between the two buildings on your right. Grind on the left rail to start the earthquake.
