Snowy Canyon Shortcut:
At the second lefthand turn after the start, go straight instead of turning
and jump over the water! Proper alignment on the jump is critical. Too
much left and it's rollover time. Too much to the right and you'll land
in the water. I found this shortcut by using blimp view during a replay.
Sierra Logging Run Shortcut:
The Sierra shortcut is near the end of each lap. Just after you pass a
logging truck and some cones on the right, (the track is paved at this
point), go straight thru a barrier instead of turning right and jump over
the rocks.
Have fun!
