In you ski and snowboard where are the secret spots

I have not found all of the spots yet but here are a few:
- Go to the top on Mt. Angrio and turn around start skiing until you reach the top. Keep going upwards, eventually you can not go any further and it will tell you, you found a secret spot. You may need to side-step to get to the top.
- When your on the Kangaroo path go down straight past the rails and such, when you get to a small area stop. In the area should be lift 3. Go to the building names Dannys Dogs and go up the stairs to to top. This may require side-stepping. When you get there it will tell you, you found a secret spot. Also a strange little girl is found at the top as well.
I dont want to ruin the game for you so I'm not going to say the rest just go around and have fun searching! (:
