If you can ski correctly and are having fun, you aren't a noob. For park, if you know guidelines and unofficial rules (getting out of the way of the landing) and can do a basic grind and straight air 20-25ft jumps id say your are doing fine. Make sure to learn grinds and spins both ways.
the division between noob and normal person is always moving, maybe youre not a noob if this was like 2012 but in 2015?! you better start throwin some 450s and some cork 7s if you want to not be called a noob
If he was an mma fighter his name would be "Nick butterysmooth goepper"
