Extreme Boards and Blades
Use the skateboard and get on the obstacle.
Then, without moving, hold [Grind]. Next, tap [Push]
to grind slowly. If the coping or curb is long, you
will have enough points to complete the level.
Here are two awesome tricks that will get you 800+ points.
These tricks are spin moves. You can do more than 360's as
long as you hold them:
360 Maddonna: Ollie, A+W+F
360 Backflip: Ollie, A+W+D
